regulator: Fixes for v3.13

Browse Source 
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.
