Skeleton driver for the LG GP40NW10 USB DVD writer [O. Galibert]

It is (was?) an inexpensive dvd writer.  I started this driver to see
if it was possible to add commands for really raw reading.  Let's just
say that mcs51 code is a pain to read.

If it ever works, it can be interesting as a USB device for when we
end up insane enough to try to handle USB in the first place.
