Initial console device driver for USB displays based on the DisplayLink

DL-120 / DL-160 graphic chips, using the wsdisplay(4) layer.  Based on
the reversed engineered specifications of Florian Echtler.  The driver
is disabled in GENERIC for now.

Thanks to claudio@ for donating me a device and to oga@ and miod@ for
giving me hints in the graphic and wsdisplay area.

OK deraadt
