regulator: Updates for v4.1

Browse source 
Another release, another set of regulator updates.  Not much of it is
 showing up in the code yet but there's been a lot of discussion going on
 about how to enhance the regulator API to work better with modern SoCs
 which have a microcontroller sitting between Linux and the hardware.
 I'm hopeful that'll start to come through into mainline for v4.2 but
 it's not quite there for v4.1 - what we do have (along with the usual
 small updates is) is:
 
  - Work from Bjorn Andersson on refactoring the configuration of
    regulator loading interfaces to be useful for use with
    microcontrollers, the existing interfaces were never actually useful
    for anything as-is since nobody was willing to put enough data into
    public code.
  - A summary tree display in debugfs from Heiko Stübner.
  - Support for act6000 regulators.
