  Log:
  Attempt to fix and document interactions between suspend/resume and pccardc
  power x 0.
  
  pccardc power x 0 used to disable the slot.  But a suspend/resume
  would reactivate the pccard.  It no longer does that.  Now the
  disabling of the slot is sticy until it is reset with power x 1 or the
  card is ejected.  This seems closer to correct behavior to me.
  
  o Process all card state changes the same using pccard_do_stat_change().
  o Cleanup disabling the card so that we can preserve the state after
    the change.  Basically, don't set it to empty as often as we do.
  o On suspend, the new state is "empty" and the laststate is "suspend"
  o Document state machine with a diagram of states and edges.  The
    edges are labeld to tell the reader what event causes the external
    state changes.
  o "machdep.pccard.pcic_resume_reset" may be obsolete now.  We always
    call the bridge driver's resume method on resume now.  Otherwise cards
    won't automatically show up.  If it needs to stay, I'll add it back.
