Eldar and Orks were created by the same beings. Not even a 'hint' or shifty reading. It is actual canon. Both races developed to fight the Necrontyr.
Gork is Khaine, Mork is Cegorach.

They are not Chaos Gods, and the presence of Chaos is anathema to them.

Ynnead appears to be a whole new breed of Eldar God, unrelated to the Old Ones, with a little too much in common to a Chaos God. But, everyone knows that the Aeldari were secretly Chaos worshipping scum and always have been.
Gotta disagree with you very strongly here. The belief that the Old Ones, C'Tan, and the Eldar/Ork gods are all the same beings seems to be unique to you Cheesegear. The Eldar/Orks gods are based on echoes of the deeds of said beings, but they are emphatically not the same creatures.

Here's my two(thousand) cents:
Spoiler: The War/s in Heaven
Show
The Eldar and Orks were created by the Old Ones, who though astoundingly proficient in Immaterium-based technology, were not entirely from that realm like the Chaos Gods. They possibly used the same circular-reincarnation trick that the High Eldar and Ancient Human Shamans practised. There's also an outside possibility they were like the Enslavers, which have a life-cycle that partly takes place in the warp and partly in realspace (kind of like turtles laying eggs on beaches, if the sea was the warp and the beach was reality, and the eggs were incubated inside a human soul).

Before the War in Heaven, the Immaterium was a pretty peaceful place. It is the realm of the soul and the collective unconscious, so when the Old Ones were the only sentient life in the galaxy it was mostly just a white void (contrasting with Realspace's black void), a blank canvas awaiting a shape. Then the Old Ones started spreading life across the galaxy and the Immaterium became less empty, turning into a dreamland of sorts, made of bubbles of different race's ideas of reality butting against each other.

Then the Necrontyr came along and ruined it all. They and the C'Tan (who explicitly have nothing to do with the Immaterium, and quite likely predate the Old Ones) set about systematically slaughtering the Old One's creations. This had several terrible effects on the Immaterium. Firstly, it flooded it with souls who died in pain and anguish. Secondly, as the Old Ones mobilised the races of the Galaxy to fight back it gets flooded with emotions of anger and hate, a desperate need to survive and a desire for control. Thirdly, as the Nightbringer personally consumes entire races the image of a Dread Reaper gets burned into it, traumatising pretty much every race forever.

The Old Ones see what's happening in the now rather turbulent Warp, and decide the best thing to do is weaponise it. This proves to be a terrible idea long-term, but they were in a fight for the survival of organic life, so they probably thought they'd fix any repercussions down the line. So, a number of Old Ones start breeding up a selection of races across the galaxy with very strong connections to the Warp. One of the first successful versions are the race that will become the Eldar, and the Old Ones who created them speak to them personally to prime them for the war to come. One of the last was the K'Orks, but the war ended before the Old Ones in charge could finish them properly (they were likely intended to be foot soldiers for the Eldar to command psychically). Also, at some point someone (likely the Old Ones, but maybe the Eldar or even the Necrons) build the Blackstone Fortresses, designed to fire beams of pure warp energy into stars and kill the C'Tan who live there (incidentally making the star explode).

So, the Galaxy is now in a constant churning war, with the most intense fighting involving highly psychic races and Old Ones clashing with Necron and C'tan. The witnessing, emotional connection to, and constant re-telling of these events begins to have an effect in the Warp: where the Eldar and Orks witness the trickery of the Deceiver and/or Old Ones, they tell of Cegorach and Mork. Where they witness carnage and victory, they tell of Khaine and Gork. And these dreams (and many others, from other races and Old Ones) clump together in the warp, forming the nascent bodies of the first Warp Gods.

Unfortunately for pretty much everyone, the war ends in a brutal series of deathblows. Firstly, the Necrons and C'tan finally break into the webway, and hunt down and butcher almost all of the Old Ones. Then at the moment of victory, the Necrons turn on their C'Tan masters and backstab them with all the WMDs they have. With their dying breath the C'Tan curse Zoidberg the Necrons with a variety of awful things: The Flayer Virus (Llandu'gor the Flayer), the Destroyer Curse (the Nightbringer), and a form of Robot Alzheimers (probably from the Deciever, he's that kind of *******). Most of their armies and WMDs expended, and with an expanding and enraged High Eldar empire intent on their destruction, the remaining Necrons decide hiding in a hole is the better part of valour, and vamoose.

So the Eldar and K'Ork are left with very little to do, and a galaxy mostly depopulated of sentient life. Or rather, the Eldar are left with not much to do: the Orks know exactly what they were put in the galaxy for, "Fightin' an Winnin'!". So they proceed to do just that, fighting the Eldar, everyone else, and themselves depending on who's nearest. It's during this period of upheaval and shifting powers, the Eldar and Ork Gods manifest fully. Since they came from echoes of the Old Ones and C'Tan, these new gods continue to play out the same mythic cycles of build up, destruction and betrayal. This culminates in the Eldar Pantheon re-enacting the War In Heaven, but this time with Khaine driven to attack his fellow deities. This is the main reason for much of the confusion about this period of history: the Eldar are the only ones who have any memory of that time, and in the past million of years of chinese-whispers the original events became indelibly mixed with their echoes.

Then later on Man appears, spreads across the galaxy breeding and dying, and the warp floods with yet more awful emotions. Remember that anger, desperation, and control I mentioned back in paragraph three? Whoops, it turns out that all the New Gods were built on these clouds of emotional instability, and like the formation of a black hole the whole lot starts collapsing in on itself towards a denser state. All those War feelings all the various minor races have? Boom: they're all Khorne now, and the name of your personal war-god is just another name for him. All gods of Scheming are now Tzeentch, all gods of Despair are Nurgle. The Eldar and Ork pantheons are the only ones to resist assimilation, because they've been around the longest and had the most dedicated followers.

Then Slaanesh exploding into being and tore the galaxy a new one. This was the finale on top of millennia of absorbing and eating all other pantheons, and finally brings the Eldar low. Slaanesh has as part of xir purview "eating all Eldar, including their gods", and quickly devourers and consumes almost all of them. There two exceptions: first Khaine, for whom Khorne had always craved to assimilate. So he fights Slaanesh over him, like two spoiled children with one GI Joe toy, and Khaine literally explodes. His essence is scattered to the wind, and ends up fleeing the warp and finding a home at the centre of each nascent Craftworld. Secondly, Nurgle had always been in love with Isha, goddess of Life. So he steals her away from Slaanesh at the last moment, and locks her in his garden.

And there we have it. The state of play in the 41st Millenium, with evil gods being the only ones left. Oh yes, and now the Tyranids have arrived. Because when a galaxy pollutes its section of the warp into tearing holes into realspace, you can bet someone will take notice and send in the clean-up crew. This wasn't the only evolution of Materium-Immaterium interaction possible, and those who took different, more successful routes, take a dim view of some jumped-up nobodies perhaps dooming the universe to an early extinction.


So yeah. Khaine, Khorne, and Gork are all echos of the concept of "fighting". But different echoes, formed at different times. Khorne would love to be the only one, but no god of fighting has ever gone down easy.
