Got a LaserWave CD controller working

[Jeremy Fitzhardinge jeremy@suede.sw.oz.au]

Hi all,

I've got the CD interface on my LaserWave Nucleus to work properly
under Plan 9.   The patch to devsbcd.c follows - it works for me, but I
haven't thought about doing it cleanly to coexist with a real SB CD
interface, so it shouldn't be applied unless you're trying to get
something like a LaserWave, LaserMate, or some other CD-only card
working.  However, adding an INFO port as distinct from the DATA port
seems like a good general change.
