regulator: Changes for v4.19

The biggest set of changes in here is the addition of the Qualcomm RPMH
 driver.  As well as the regualtor driver itself being quite large due to
 the usual involved Qualcomm regulator stuff there's also some code
 shared with the arm-soc tree, a bus driver required to communicate with
 the hardware that actually winds up being much larger than the regulator
 driver itself and a LLCC driver that was part of the same signed tag
 used with the arm-soc tree.
 
 Other than that it's a fairly standard and quiet release, highlights
 include:
 
  - Addition of device links from regulator consumers to their
    regulators, helping the core avoid dependency issues during suspend.
  - Support for the entertainingly innovative suspend implementation in
    the BD9571MWV.
  - Support for switch regulators on the PFUZE100, this required two goes
    due to backwards compatibility issues with old DTs that were
    discovered.
  - Support for Freescale PFUZE3001 and SocioNext UniPhier.
  - The aforementioned Qualcomm RPMH driver together with the driver
    changes required to support it.
