The machine specific regulator_init() appears to be unused.
It does not allow a lot of interaction with the regulator framework,
since nothing from the framework is passed along (desc, config,
etc ...)

Machine specific init may also be done with the added init_cb() in
the regulator description, so remove regulator_init().
