drm/amd/display: Pass DSC slice height to PSR FW
[Why]
When DSC is enabled, the PSRSU seletive update region
must be multiple number of DSC slice height number.
The original solution is to overwrite the SU Y granularity
by DSC slice height in DAL driver. However, the size
of the SU Y granularity variable only has 8 bytes
and the DSC slice height may over the 8 bytes size.
[How]
Instead of overwriting the SU Y granularity value,
add a new DSC slice height pararmeter and pass it
to DMUB PSRSU FW. The PSRSU FW will refer to the
DSC slice height value and extend the SU region.
