regulator: move bq24022 init back to module_init instead of subsys_initcall

This workaround was needed when regulator/ was not linked before both
power/ and usb/otg/ in drivers/Makefile. Now that it is even linked
before mfd/, this patch makes sure that bq24022 isn't probed before the
GPIO expander is set up.
