pxa27x disconnects pullups on suspend but doesn't notify the gadget driver about it, so gadget driver can't disable the endpoints it was using. This causes problems on resume because gadget core will think endpoints are still enabled and just ignore the following usb_ep_enable(). Fix this problem by calling gadget_driver->disconnect().
