drm: Add drm/drm_util.h header file
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. v2: Rename to drm_util.h instead (Dave&Sean) Cc: Sean Paul <seanpaul@chromium.org> Acked-by: Sean Paul <seanpaul@chromium.org> Cc: Dave Airlie <airlied@gmail.com> Acked-by: Dave Airlie <airlied@gmail.com> Signed-off-by: Daniel Vetter <daniel.vetter@ffwll.ch> Link: https://patchwork.freedesktop.org/patch/msgid/20180905135711.28370-1-daniel.vetter@ffwll.ch
