Warner Losh 2cb5caa767 Latest incremental efforts on newcard:
o Delete pcic1 from NEWCARD
o Add explicit resource hints to pcic0
o Get attach working with newbus, kinda (it does all the newbus stuff,
  but doesn't try to attach the pccard yet, too many panics).
o Disable ie0 and le0 in NEWCARD config.  There appears to be a bug in
  the isa_compat code wrt memory conflicts with newbus drivers for
  reasons unknown.
o Minor cleanups.
