The supposed OLD STYLE network MAC id tuple was really just a buggy
expression in the card in question. Since that driver uses a
different mechanism, retire the workaround for this bug.

Some older PC Cards have a weird format for FUNCE tuples. They appear
as type 0, rather than the usualy type 4. Assume that this format is
from an old standard and go with it. The Fujitsu FMV-186A and Silicom
Ethernet cards I have both have tuples with this format, and they are
both pretty old cards.

Add new file for definitions of CIS. We can share this with cardbus.
the filename isn't that bad, because all of these are defined in the
PC Card standard :-)
