Paolo Bonzini 4700a316df pc: port 92 reset requires a low->high transition 
The PIIX datasheet says that "before another INIT pulse can be
generated via [port 92h], [bit 0] must be written back to a
zero.

This bug is masked right now because a full reset will clear the
value of port 92h.  But once we implement soft reset correctly,
the next attempt to enable the A20 line by setting bit 1 (and
leaving the others untouched) will cause another reset.
