drm/i915/dp: Use connector DSC DPCD in i915_dsc_fec_support_show()

Use the connector's DSC DPCD capabilities in i915_dsc_fec_support_show()
instead of the version stored in the encoder. Atm the two are identical,
but a follow-up patch will store the (MST) connector specific version
in the connector.
