drm/amd/display: Added locking for atomic update stream and update planes
[Why] Screen flickering when HDR switches between FP16 and ARGB2101010 [How] Moved pipe_control_lock so stream update and plane update occur atomically Signed-off-by: Anthony Koo <Anthony.Koo@amd.com> Signed-off-by: Lucy Li <lucy.li@amd.com> Reviewed-by: Aric Cyr <Aric.Cyr@amd.com> Acked-by: Bhawanpreet Lakha <Bhawanpreet.Lakha@amd.com> Signed-off-by: Alex Deucher <alexander.deucher@amd.com>
