usb-device: Allow signaling capability of remote_wakeup. 

To use this feature you need to create a usb device signaling remote wakeup
and then enable remote wakeup on the host (on linux write enabled to
/sys/bus/usb/devices/<device>/power/wakeup). Then you can wake up the host
when is on standby using USBDevice.remote_wakeup.
