    sys/isa              sio.c

  Log:
  Fix the hang on card eject problem and maybe the hang on suspend
  problem.
  
  o Create new timeout routine so we don't detach the card inside a ISR
    but instead drop back to spl0 via a timeout of 0.
  o Actually delete the child of the pccard device rather than just faking
    it badly.
  o Fix sio, ed and ep to have pccard detach routines that are int rather
    than void.
  o Fix ep and ed pccard detach routines to use if_detach rather than just
    if_down.  if_detach destroys the device, while if_down just marks it
    down.  In this incarnation of the pccard things, we map the disable
    the slot action to detach the driver, which removes the driver from the
    device tree.  When that is done, a panic would soon follow as the
    ifconfig tried to down the device.
  
  Didn't fix:
  o Should cache the pccard dev child's pointer in struct slot
  o remove now unused parts of struct slot
  o Any driver using softc after detach has been called.  sio's softc used
    to be statically allocated, so you could check sc->gone, but that is
    now gone.
  o Didn't remove gone from softc of drivers that use the old pccard method.
  
  Didn't test:
  o ed driver changes
  o sio driver changes on pccards
  o suspend (no laptop or apm support on my desktop)
