Pull regulator fixes from Mark Brown:
 "A small set of driver fixes plus one larger core change which changes
  the way we check to see if we're using DT so that there aren't any
  races between deciding we're using DT and the regulator subsystem
  noticing.

  This makes the new support for substituting a dummy regulator and
  optional regulators work a lot better on DT systems since it ensures
  that we don't trigger probe deferral when we shouldn't which was
  causing bugs in clients"
