I don't think this really does anything since the interrupts shouldn't
really be "hanging around" when a PIO transfer starts and that's the
only place it's used. I suspect we could actually fully remove that
bit of "Ack any previous interrupts that might be hanging around" code
and everything would be fine.

In any case, I don't have any huge objections, thus:
