gpio-button-hotplug: do not error on interrupt attached keys
The Linux gpio-keys driver bindings allow for GPIO attached or interrupt
attached keys. Currently if an interrupt attached key is encountered
gpio_keys_button_probe() will fail due to not being able to get a gpio
descriptor:
gpio-keys: probe of gpio-keys failed with error -2
Skip the failure in the case of interrupt attached keys to resolve this.
