From: Andrey Grodzovsky <andrey.grodzov...@amd.com>
Modify amdgpu_dm_atomic_comit to implement
atomic_comit_tail hook.
Unify Buffer objects allocation and dealocation
for surface updates and page flips.
Simplify wait for fences and target_vbank logic
for non blockiing commit.
Remove hacky update surface to page flip synchronization
we had and rely on atomic framework synchronization logic.
