[RFC PATCH 4/5] drm/amd/display: hook DCN30 color state logging to DTN log

Tue Sep 5 14:25:44 UTC 2023
Color caps changed between HW versions which caused DCN10 color state
sections on DTN log no longer fit DCN3.0 versions. Create a
DCN3.0-specific color state logging and hook it to drivers of DCN3.0
family.
