drm/amd/display: Disable DSC power gating in Diags

Browse Source 
[why]
With DSC power gating enabled, one of the register reads times out occasionally,
causing a DSC test to fail.

[how]
Disable DSC power gating in Diags.
NOTE: This has to be reverted once the problems with DSC power gating are
resolved.
