[Why]
If psr_feature_enable is set to true by default, it continues to be enabled
for non capable links.
[How]
explicitly disable the feature on links that are not capable of the same.

Patch which added graceful exit for non-persistent contexts missed the
fact it is not enough to set the exiting flag on a context and let the
backend handle it from there.
GuC backend cannot handle it because it runs independently in the
firmware and driver might not see the requests ever again. Patch also
missed the fact some usages of intel_context_is_banned in the GuC backend
needed replacing with newly introduced intel_context_is_schedulable.
Fix the first issue by calling into backend revoke when we know this is
the last chance to do it. Fix the second issue by replacing
intel_context_is_banned with intel_context_is_schedulable, which should
always be safe since latter is a superset of the former.

DCN provides a hook to check if we can have a new pipe allocation based
on some DC constraints. If the current configuration supports the new
pipe request, DC updates its context; otherwise, it will keep the same
configuration. This behavior is similar across multiple ASICs, and for
this reason, we reused DCN20 on DCN321. However, this DCN32x has some
peculiarities which require its function to avoid weird pipe split
issues. This commit update this issue by using

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
