[PATCH 4/4] amd/display: indicate support for atomic async page-flips on DCN

[Simon Ser]

amdgpu_dm_commit_planes already sets the flip_immediate flag for
async page-flips. This flag is used to set the UNP_FLIP_CONTROL
register. Thus, no additional change is required to handle async
page-flips with the atomic uAPI.

Note, async page-flips are still unsupported on DCE with the atomic
uAPI. The mode_set_base callbacks unconditionally set the
GRPH_SURFACE_UPDATE_H_RETRACE_EN field of the GRPH_FLIP_CONTROL
register to 0, which disables async page-flips.
