regulator: devres: add API for reference voltage supplies
A common use case for regulators is to supply a reference voltage to an
analog input or output device. This adds a new devres API to get,
enable, and get the voltage in a single call. This allows eliminating
boilerplate code in drivers that use reference supplies in this way.
