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.
