usb: interface authorization: Introduces the USB interface authorization
The kernel supports the device authorization because of wireless USB.
These is usable for wired USB devices, too.
These new interface authorization allows to enable or disable
individual interfaces instead a whole device.
If a deauthorized interface will be authorized so the driver probing must
be triggered manually by writing INTERFACE to /sys/bus/usb/drivers_probe
