drm/amd/display: Add pstate verification and recovery for DCN31

[Why]
To debug when p-state is being blocked and avoid PMFW hangs when
it does occur.

[How]
Re-use the DCN10 hardware sequencer by adding a new interface for
verifying p-state high on the hubbub. The interface is mostly the
same as the DCN10 interface, but the bit definitions have changed for
the debug bus.
