I've picked up a few more patches I couldn't find anything to bikeshed
about, the others grew some comments. I haven't looked too hard at the
actual modeset stuff given that you're already really busy reworking
things and moving stuff to intel_ddi.c

For the modeset stuff 2 general comments so you know from where the
bikeshed will hit you in the next review round:
- if possible, I'd like to hide most of the 'disable pch stuff on hsw'
  stuff behind crtc_driving_pch checks.
- I think we need to be careful about IS_HASWELL vs PCH_LPT checks,
  otherwise hsw+ppt will not work so great.

For the dip/infoframe stuff, maybe you can volunteer Paulo to help you
out, he's looking into this atm anyway. 

Cheers, Daniel
