Support for the LED of the U2F Zero device.
U2F Zero supports custom commands for blinking the LED
and getting data from the internal hardware RNG.
The internal hardware can be used to feed the enthropy pool.
U2F Zero only supports blinking its LED, so this driver doesn't
allow setting the brightness to anything but 1, which will
trigger a single blink and immediately reset back to 0.
