drm/amd/display: add dummy pstate workaround to dcn315
DCN315 has to always allow pstate change or SMU will hang. This
workaround achieves this by applying a low pstate change latency
to be used when pstate is calculated to be unsupported. This lower
latency only accounts for memory retraining; a previous change
handles locking in the highest available pstate allowing us to minimize
required latency hiding to only account for memory retraining.
