drm/amd/display: Defer BW-optimization-blocked DRR adjustments
[Why & How] Instead of dropping DRR updates, defer them. This fixes issues where monitor continues to see incorrect refresh rate after VRR was turned off by userspace. Fixes: 32953485c558 ("drm/amd/display: Do not update DRR while BW optimizations pending") Link: https://gitlab.freedesktop.org/drm/amd/-/issues/3546 Reviewed-by: Sun peng Li <sunpeng.li@amd.com> Signed-off-by: John Olender <john.olender@gmail.com> Signed-off-by: Aurabindo Pillai <aurabindo.pillai@amd.com> Signed-off-by: Ray Wu <ray.wu@amd.com> Tested-by: Daniel Wheeler <daniel.wheeler@amd.com> Signed-off-by: Alex Deucher <alexander.deucher@amd.com>
