USB: pxa27x_udc: add vbus session handling
On vbus_session() call, optionally activate D+ pullup resistor and enable the udc, or deactivate D+ pullup resistor and disable the udc. It is intentional to not handle any VBus sense related irq. An external transceiver driver (like gpio_vbus) should catch VBus sense signal, and call usb_gadget_vbus_connect() or usb_gadget_vbus_disconnect().
