[PATCH 01/14] drm: Add drm/kernel.h header file

[Daniel Vetter <daniel.vetter@ffwll.ch>]

We have a bunch of neat little macros all over the place which should
move to kernel.h. But some of them died in bikesheds on lkml, and we
need a decent home for them.

Start out by moving the for_each_if macro there.
