Should this be split up into 3 patches? At least it's good practice to
split up the drm core helper functions into it's own patch, instead of
hiding it behind something with the drm/imx prefix - no one will spot it
that way.

If imx maintainers keep being asleep at the helm I can merge this through
drm-misc, but I'd like some more tested-by from other folks if possible.
Even better when there's a review.
