drm/amd/display: Add missing CW4 programming for DCN30
[Why]
To support inbox1 in CW4 we need to actually program CW4 instead of
region 4 for newer firmware.
This is done correctly on DCN20/DCN21 but this code wasn't added to
DCN30.
[How]
Copy over the missing code. It doesn't need address translation since
DCN30 uses virtual addressing.
