Warner Losh 109c00c9ee Implement sn_pccard_match. The match routines are the compromise
matching methods so that we can run the same driver on both NEWCARD
and OLDCARD.  Also set the device description to the card that we
found, if any.

The sn driver should be ready when the NEWCARD catches up.  There's a
config activation issue as well as a kernel thread issue to resolve
first.
