drm/amd/display: fix PSR-SU/DSC interoperability support

Browse source

[ Upstream commit 13b90cf900 ]

Currently, there are issues with enabling PSR-SU + DSC. This stems from
the fact that DSC imposes a slice height on transmitted video data and
we are not conforming to that slice height in PSR-SU regions. So, pass
slice_height into su_y_granularity to feed the DSC slice height into
PSR-SU code.
