This looks mostly good, the only big thing is this - the default is to
just unconditionally register all the regulators that exist rather than
only those that are configured on that particular platform.  This is a
bit simpler and means that all the readback of the configuration for the
unconfigured regulators is available for diagnostics.  Is there a reason
not to do that?
