gpio: return -ENOTSUPP if debounce cannot be set
It appears some drivers are using gpio_set_debounce() opportunistically, i.e. without knowing whether it works or not. (Example: input/keyboard/gpio_keys.c) to account for this use case, return -ENOTSUPP and do not print any warnings in this case. Took a round over the other gpio_set_debounce() consumers to make sure that none of them are relying on the returned error code to be something specific.
