move implemenation from ttm to amdgpu driver. (suggested by Christian)
per-vm-lru is because of per-vm-bo, which has no chance to refresh lru, the
nagtive effect is game performance isn't stable.
so all per-vm-bo should have a default order, every per-vm-bo has its
priority, relying on its creation index.
When doing CS, if any normal bo is used, then all per-vm-bo should be used,
so per-vm-bo prioirty >= normal bo priority.
Above is per-vm-lru starting point.
How do you think that we create the per vm bo as priority 1 and kernel bo as
priority 2 accordingly?
Yeah, then how to fix per-vm-bo order? I think we need set priority for every
per-vm-bo. Because of lacking bo list, the per-vm-bo lru can only depend on
priority.
Mmm, maybe use RB tree for BOs in priority 1 lru.
but it actually works for per dev rather than per vm.
Seems we need per vm lru as the patches for per vm bo management.

Will that help to make some improvement?
