This is basically fine but the regulator API has moved on a bit with the
DT handling over the time you've been working on this.

Put this after the --- as covered in SubmittingPatches.

I'm not sure factoring out the code actually won much here.

We now have helpers in the regulator core for this - set of_match and
regulators_node in the regulator descriptor and the core will resolve
this stuff for you and...

...you can just drop the else case (and check for reg_init_data) here.
