Merge tag 'topic/drm-misc-2016-08-31' of git://anongit.freedesktop.org/drm-intel into drm-next

More -misc stuff
- moar drm_crtc.c split up&documentation
- some fixes for the simple kms helpers (Andrea)
- I included all the dri1 patches from David - we're not removing any code
  or drivers, and it seems to have worked as a wake-up call to motivate a
  few more people to upstream kms conversions for these. Feel free to
  revert if you disagree strongly.
- a few other single patches
