The current handling of the subtraction insn with the RND12 modifier
works when saturation isn't involved. So add handling for this edge
case to match the hardware.

We need the DIR bit cleared, not set, in order for the pin to be treated
as an input.
When looking up the data value, we need to shift the "level" value over by
"my_port" rather than "bit" as the latter has already been shifted over.
We also should normalize the "level" coming in from the outside worlds to
the set of {0,1} since those are the only values that matter to GPIOs.
We need the BOTH bit set, not cleared, in order for the pin to trigger
on both edges.

The clear/set/toggle MMRs aren't backed by "real" data; they implicitly
perform bit operations on the associated data register. So when we go
to process writes to them, we need to adjust the pointer accordingly so
that the actual backing data is modified.
