dt-bindings: input: gpio-keys: Fix interrupts in example
The "interrupts" property in the example looks weird:
- The type is not in the last cell,
- Level interrupts don't work well with gpio-keys, as they keep the
interrupt asserted as long as the key is pressed, causing an
interrupt storm.
Use a more realistic falling-edge interrupt instead.
