USB in Genode 18.08

[Edward Sandberg]

I was very excited to see that the 18.08 release notes indicated that
the USB driver is available for the Wandboard Quad.  Unfortunately my
testing has not been successful yet. I can build run/usb_hid with the
seL4 kernel but at boot time I see:

Genode 18.08

and that last line repeats indefinitely. I cannot find either of those
addresses anywhere in the code so it is unclear to me what the problem is.
