drm: Split out drm_probe_helper.c from drm_crtc_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.
