If the GPIO block supports it, GPIO provides an API to use a hardware
I'e had exotic ideas like pulling the debounce support from the input
subsystem into the GPIO subsystem, so whenever a consumer asks
for debounce they will get it, sometimes with a software timer
sometimes from hardware. But it never became any more than a
