Rework the card insertion/removal detection logic:
- instead of queueing events each time the sense information changes,
only remember that the slot needs attention
- when processing a slot needing attention, decide what to do depending upon
its current sense information, rather than what it was when the change
was detected
- handle the ``only one sensor asserted'' state happening during slow
insertion or removal.
This makes the driver much more reactive to insertions and removals, and
also removes unnecessary attach/detach calls.
