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. Signed-off-by: Felix Dörre <[email protected]>
