drm/i915: Allow "max bpc" property to limit pipe_bpp
Use the newly added "max bpc" connector property to limit pipe bpp.
V3: Use drm_connector_state to access the "max bpc" property
V4: Initialize the drm property, add suuport to DP(Ville)
V5: Use the property in the connector and fix CI failure(Ville)
V6: Use the core function to attach max_bpc property, remove the redundant
clamping of pipe bpp based on connector info
V7: Fix Checkpatch warnings
V9: Cleanup connected_sink_max_bpp and fix initial value in DP(Ville)
V12: Fix debug message(Ville)
V13: Remove the redundant check and simplify the check logic(Stan)
V14: Fix the check in connected_sink_max_bpp(Stan)
v15 (From Manasi): Add missing break (Stan)
