o Add routines to return the location and pnpinfo for this card.
Note, we return the PCI pnp info, but in fact that's wrong to do
since that data is not defined for CardBus cards. CardBus says that
these registers are undefined and one should use the CIS to do
device matching. To date, all CardBus cards have had these
registered defined, no doubt because they are using common silicon
to produce both the PCI cards and the CardBus cards. However, it isn't
any worse than the rest of the system, so just note it in passing and
move on.
o Also sort prototypes while I'm here.
