Both of the above info is available already in the connector's
i915_dsc_fec_support debugfs entry. As I understood the aim is having
each CRTC / connector show its own properties, instead of combinining
all those into one debugfs entry (as this is done in i915_display_info).
Based on that I don't think more (duplicated) information should be
added here.
One issue with the i915_dsc_fec_support entry is that it doesn't show
the sink capabilities if the output isn't enabled on the connector, I
plan to follow up with a fix for that.
