Pull regulator fixes from Mark Brown:
 "A collection of fixes for the regulator API that have come up since
  the merge window, including a big batch of fixes from Axel Lin's usual
  careful and detailed review.

  The one stand out fix here is Dmitry Baryshkov's fix for an issue
  where we fail to power on the parents of always on regulators during
  system startup if they weren't already powered on"
