Dillon Varone 89713ce551 drm/amd/display: Enable Request rate limiter during C-State on dcn401 
[WHY]
When C-State entry is requested, the rate limiter will be disabled
which can result in high contention in the DCHUB return path.

[HOW]
Enable the rate limiter during C-state requests to prevent contention.
