drm/i915/dp_mst: Set connector DSC capabilities and decompression AUX

Browse source

Similarly to eDP and SST-DP connectors read out the DSC capabilities for
MST connectors as well. Atm these will match the root port's DSC caps
and only used after a follow-up change enables the decompression for
each stream separately (vs. the current way of enabling it only globally
in the first branch device downstream of the root port).
