Update pull request with drm core patches. Mostly some polish for the
primary plane stuff and a pile of patches all over from Thierry. Has
survived a few days in drm-intel-nightly without causing ill.
I've frobbed my scripts a bit to also tag my topic branches so that you
have something stable to pull - I've accidentally pushed a bunch more
patches onto this branch before you've taken the old pull request.

drm/plane-helper: Fix primary plane scaling check
drm: make mode_valid callback optional
drm/edid: Fill PAR in AVI infoframe based on CEA mode list
Many drm connectors do not need mode validation.
The patch makes this callback optional and removes dumb implementations.
v2: Rebase:
- imx move to a shared (but still dummy) ->mode_valid implementation.
- probe helpers have been extracted to drm_probe_helper.c

This is leftover stuff from my previous doc round which I kinda wanted
to do but didn't yet due to rebase hell.
The modeset helpers and the probing helpers a independent and e.g.
i915 uses the probing stuff but has its own modeset infrastructure. It
hence makes to split this up. While at it add a DOC: comment for the
probing libraray.
It would be rather neat to pull some of the DocBook documenting these
two helpers into in-line DOC: comments. But unfortunately kerneldoc
doesn't support markdown or something similar to make nice-looking
documentation, so the current state is better.
