drm/amd/display: Fix DCN42 null registers & register masks

Browse source

[why]

The register lists used on DCN42 variants are different. Some reused
codepaths are trying to access registers not used.

[how]

Add DISPCLK_FREQ_CHANGECNTL, HUBPREQ_DEBUG, and HDMISTREAMCLK_CNTL to
the register lists.
