Subject: [PATCH v6 4/6] amd/display: indicate support for atomic async page-flips on DC

From: Simon Ser <contact@...rsion.fr>

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.
