Imre Deak 70a6587dca drm/dp_mst: Fix DSC decompression detection in Synaptics branch devices 
Atm it's assumed that all Synaptics MST branch devices support DSC,
which is not exposed via a DP-to-DP peer device, rather a control flag
in the branch device's UFP DPCD applying to all the streams going
through it. This isn't true for all adapters with this branch device
though (for instance the Cakitte USBC->2xHDMI adapter reported in the
Closes link below doesn't support DSC).

Fix the above by advertising the DSC decompression support only if the
capability flag for this in the UFP DPCD is actually set.
