regulator: stub: Export init function for early probe

Some usecases of stub-regulator require the regulator devices to
be probed early on. As a consequence, allow for stub-regulator
to be added at a custom time by the platform code. Simply
changing the init level of this driver is not enough. We must
allow for other drivers added at the same init level to be
dependencies or dependents of this driver.
