We had several attempts at gpio_keys and adding a polled mode and we
ended up with the driver getting too complex and having unwanted
dependencies. At the moment I believe that the split between gpio_keys.c
and gpio_keys_polled.c is justified even it it may lead to certain code
duplication.

However, if DT bindings are really the same we could split them off into
a separate library module used by both drivers.

Thanks.
