usb: ulpi: Automatically set driver::owner with ulpi_driver_register()
Let's follow other driver registration functions and
automatically set the driver's owner member to THIS_MODULE when
ulpi_driver_register() is called. This allows ulpi driver writers
to forget about this boiler plate detail and avoids common bugs
in the process.
