The previous patches converted all users of the DSC DPCD caps to look
these up from the connector, so remove the version stored in intel_dp.
A follow-up patchset will read out the MST connector specific
capabilities in intel_dp_add_mst_connector() ->
intel_dp_mst_read_decompression_port_dsc_caps().
v2:
- Rebased on intel_edp_get_dsc_sink_cap() addition in the patchset.
