Ville Syrjälä dbd4d5761e drm: Replace 'format->format' comparisons to just 'format' comparisons
Rather than compare the format u32s of two format infos, we can direclty
compare the format info pointers themselves. Noramlly all the ->format
pointers all point to somwehere in the big array, so this is a valid
way to test for equality.

Also drivers may want to point ->format at a private format info struct
instead (eg. for special compressed formats with extra planes), so
just comparing the pixel format values wouldn't necessaritly even work.
But comparing the pointers will also take care of that case.
