drm/amdgpu: create amdgpu_vkms (v4)
Modify the VKMS driver into an api that dce_virtual can use to create
virtual displays that obey drm's atomic modesetting api.
v2: Made local functions static.
v3: Switched vkms_output kzalloc for kcalloc.
Cleanup patches by moving display mode fixes to this patch.
v4: Update atomic_check and atomic_update to comply with new kms api.
