regulator: Updates for v5.6

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.

   redundant PCM ioctls.
