drm/amd/display: Avoid configuring PSR granularity if PSR-SU not supported

[Why]
If PSR-SU is disabled on the link, then configuring su_y granularity in
mod_power_calc_psr_configs() can lead to assertions in
psr_su_set_dsc_slice_height().

[How]
Check the PSR version in amdgpu_dm_link_setup_psr() to determine whether
or not to configure granularity.
