usb: phy: generic: remove the vbus dependency
As the last known user, ie. pxa27x_udc relying on calls to usb_gadget_xxx() was amended to use the phy notifier, remove a bit the USB stack adherence. Actually the driver still uses the gadget API for structures definition, but the implementation of USB gadget specific function usb_gadget_*() is not necessary anymore.
