Pull regulator updates from Mark Brown:
 "Hardly anything going on in the core this time around with the
  regulator API and pretty quiet on the driver front:

   - An API for comparing regulators, useful for devices that need to
     check if supply voltages exactly match rather than just nominally
     match.

   - Conversion of several DT bindings to YAML format.

   - Conversion of I2C drivers to probe_new().

   - New drivers for Monolithic MPQ7920 and MP8859, and Rohm BD71828"
