[PATCH 07/13] drm/dp_mst: Add new quirk for Synaptics MST hubs

From: Mikita Lipski Synaptics DP1.4 hubs (BRANCH_ID 0x90CC24) do not support virtual DPCD registers, but do support DSC. The DSC caps can be read from the physical aux, like in SST DSC. These hubs have many different DEVICE_IDs. Add a new quirk to detect this case. Reviewed-by: Wenjing Liu Rev
