No, we shouldn't do anything when the regulator probes - we'll only
disable unused regulators when we get to the end of boot (currently we
delay this by 30s to give userspace a chance to run, that's a hack but
we're fresh out of better ideas).  During boot the regulator state will
only be changed if some consumer appears and changes the state.
