[ Upstream commit d725ce9d7c78fb4e22c6c7676106e135ade14fa8 ]

Commit 0848814aa2 ("drm/i915/dp: Fix connector DSC HW state readout")
moved the DSC HW state readout to a connector specific hook, however
only added the hook for DP MST connectors, not for DP SST ones. Fix
adding the hook for SST connectors as well.

This fixes the following warn on platforms where BIOS enables DSC:
