Remove this driver from FreeBSD.

Remove this driver from FreeBSD.

Jonathon Lemon's driver (gx) is at least as fast and has more features
and is likely to be better supported.

It is also possible that Intel might support this chipset in FreeBSD
with their own driver. Somewhat secretive and furtive rumblings from
certain Yahoo employees have indicated that this might happen soon.

I'm a little unhappy at the lack of discussion on the net list about
this, or on developers, or on hackers, or the lack of mention on
audit. This then leaves me to try and figure out the right thing
to do.

I've concluded that the right thing to do is to remove wx from FreeBSD,
as this is probably best for FreeBSD.
