I can see why you want to extract clock setup and combine DT-parsing parts,
but the rest is not that clear. At least the clock setup split should be
a separate patch, as it seems to require massive code motion.
For eg. runtime PM setup/disable or interrupt setup, I would actually suggest
to drop the parts as they make the code harder to follow (you have
a function doing nothing but calling another one).
