The digitalPinToInterrupt() macro currently remaps the pin number to the GPIO number. This is not necessary, as most users will then use the returned value in attachInterrupt() or other similar API functions, which already perform the same remapping. The first half of the macro (the condition) does indeed require the remapping to ensure the check operates on GPIO numbers. Fixes espressif#10367.
