drm/i915/dp: Fix panel replay when DSC is enabled

Prevent enabling panel replay if the sink doesn't support this due to
DSC being enabled.

Panel replay has two modes, updating full frames or only selected
regions of the frame. If the sink doesn't support Panel Replay in full
frame update mode with DSC prevent Panel Replay completely if DSC is
enabled. If the sink doesn't support Panel Replay only in the selective
update mode while DSC is enabled, it will still support Panel Replay in
the full frame update mode, so only prevent selective updates in this
case.

v2:
- Use Panel Replay instead of PR in debug prints. (Jouni)
- Rebase on change tracking the link DSC state in the crtc state.
