drm/i915/dp_mst: Disable DSC on ICL MST outputs
Enabling DSC on ICL MST outputs is broken leading to FIFO pipe /
transcoder underruns and blank screen. On TGL+ platforms MST/DSC works -
after fixing the known issues in [1] - however to make this work on ICL
requires more work.
So far DSC on MST probably didn't get enabled for users - due to an issue
fixed by [2] - but after fixing that, DSC could get enabled, leading to a
blank screen in ICL/MST configurations which do work atm. To prevent
this disable MST/DSC on ICL for now.

v2 (Ville):
- Use DISPLAY_VER >= 12 instead of > 11.
- Explain the ICL DSC issue in code comment.
