USB: pxa27x_udc: add otg transceiver support
When a transceiver driver is used, no automatic udc enable
is done. The transceiver (OTG or not) should :
- take care of VBus sensing
- call usb_gadget_vbus_connect()
- call usb_gadget_vbus_disconnect()
The pullup should remain within this driver's management,
either by gpio_pullup of udc_command() fields.
