Nicholas Kazlauskas 3107e1a7ae drm/amd/display: Fix p-state allow debug index on dcn31
[Why]
It changed since dcn30 but the hubbub31 constructor hasn't been
modified to reflect this.

[How]
Update the value in the constructor to 0x6 so we're checking the right
bits for p-state allow.

It worked before by accident, but can falsely assert 0 depending on HW
state transitions. The most frequent of which appears to be when
all pipes turn off during IGT tests.
