[Intel-gfx] [PATCH 00/19] drm/i915: Store DSC DPCD capabilities in the connector

This patchset moves the DSC DPCD capabilities from the encoder
(intel_dp) to the connector. This is required since in an MST topology
each connector has its own version of these capabilities, allowing
to configure/enable the DSC decompression for each stream separately.

The changes are needed for a follow-up patchset, fixing the MST DSC
functionality, making it also possible to enable the BW management on
MST links. The follow-up changes are based on patches 12-25 in
