drm/amd/display: Reduce SubVP + DRR stretch margin
[Description] - Having excessively large margin causes failure in the static schedulability check in some cases for SubVP + DRR - 100us of DRR margin is sufficient based on a weeks worth of stress testing on different display configs Reviewed-by: Michael Strauss <Michael.Strauss@amd.com> Acked-by: Qingqing Zhuo <qingqing.zhuo@amd.com> Signed-off-by: Alvin Lee <Alvin.Lee2@amd.com> Tested-by: Daniel Wheeler <daniel.wheeler@amd.com> Signed-off-by: Alex Deucher <alexander.deucher@amd.com>
