imp bae3c8b51d Unify the initial card probe/attach procedure with the kldload
procedure.  There were some subtle differences before that could lead
to a variety of bugs, including resources being lost (in one case
forever).  pccard_probe_and_attach_card does this now, and includes
comments about what's going on and why, since it isn't obvious from
the code.  Please let me know if I've missed anything...

Provide a new function called pccard_select_cfe that allows drivers to
select which configuration entry to use.  This is needed for some
older pre-MFC standard cards with many functions that want to activate
all their functions by selecting alternative entries, or to work
around broken ones.  pccard_select_cfe will migrate into the
pccard_if.m interface as its interface stabilizes to keep all the
pccard drivers from referencing any symbols in the pccard.ko module
directly.

Fix a printf to refer to the right function name.
