The TCA8418 might be used using different interrupt triggers on various boards. This is not working so far because the current code forces a falling edge trigger. The device tree already provides a trigger type, so let's use whatever it sets up, and since we can be loaded without DT, keep the old behaviour for the non-DT case.
