regulator: Provide a branch for moderninzation of the PWM code

There's a new, improved PWM API which allows a lot of improvements in
the PWM regulator driver.  Since the bulk of the changes are in the PWM
API this is being managed in the PWM tree, merge pending regulator API
changes to allow this to be resolved more easily.
