This has been discussed elsewhere, but I summarize here for
transparency:

This makes some of the display registers take the NEEDS_FORCE_WAKE path
in reg reads and writes, breaking things. Rebased on top of recent
drm-intel-next-queued with Ville's IS_DISPLAYREG nuking commits this
works all right, though.

BR,
Jani.
