Alex Deucher cb9e59d7e9 drm/amdgpu: Support DRM_MODE_PAGE_FLIP_ASYNC (v2) 
When this flag is set, we program the hardware to execute the flip
during horizontal blank (i.e. for the next scanline) instead of during
vertical blank (i.e. for the next frame).

Ported from radeon commit:
drm/radeon: Support DRM_MODE_PAGE_FLIP_ASYNC

v2: drop DAL change for upstream
