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 <[email protected]> Acked-by: Qingqing Zhuo <[email protected]> Signed-off-by: Alvin Lee <[email protected]> Tested-by: Daniel Wheeler <[email protected]> Signed-off-by: Alex Deucher <[email protected]>
