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.
