Subject: [PATCH] drm/amd/display: Fix ineffective setting of max bpc property
[Why]
Regression was introduced where setting max bpc property has no effect
on the atomic check and final commit. It has the same effect as max bpc
being stuck at 8.
[How]
Correctly propagate max bpc with the new connector state.
