mailbox: Add device-managed registration functions
Add device-managed equivalents of the mbox_controller_register() and mbox_controller_unregister() functions that can be used to have the devres infrastructure automatically unregister mailbox controllers on driver probe failure or driver removal. This can help remove a lot of boiler plate code from drivers.
