regulator: Updates for v5.6

Browse Source 
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.
