drm/i915/mst: Limit MST+DSC to TGL+
[ Upstream commit 51bc63392e96ca45d7be98bc43c180b174ffca09 ]
The MST code currently assumes that glk+ already supports MST+DSC,
which is incorrect. We need to check for TGL+ actually. ICL does
support SST+DSC, but supposedly it can't do MST+FEC which will
also rule out MST+DSC.
Note that a straight TGL+ check doesn't work here because DSC
support can get fused out, so we do need to also check 'has_dsc'.
