[PATCH AUTOSEL 5.10 02/11] drm/amd/display: For stereo keep "FLIP_ANY_FRAME"

[Sasha Levin]

From: Alvin Lee <alvin.l...@amd.com>

[ Upstream commit 84ef99c728079dfd21d6bc70b4c3e4af20602b3c ]

[Description]
Observed in stereomode that programming FLIP_LEFT_EYE
can cause hangs. Keep FLIP_ANY_FRAME in stereo mode so
the surface flip can take place before left or right eye
