usb: ulpi: ulpi_init should be executed in subsys_initcall
Phy drivers and the ulpi interface providers depend on the
registration of the ulpi bus. Ulpi registers the bus in
module_init(). This could cause unnecessary bus users'
probe delays. i.e. unnecessary -EPROBE_DEFER happening on
ulpi_drivers in case they're registered before ulpi bus
itself.
