When I meant "both", I was thinking of the _single_ existing case and new one
which you are about to add. In principle, I think changing behaviour here is
undesired. We provoke BIOS writers to make mistakes with debounce settings in
GpioInt() resources.
I agree on the patch...

...except this hunk.
