Input: gpio_keys_polled - suppress deferred probe error for gpio

JIRA: https://issues.redhat.com/browse/RHEL-52234

    On a PC Engines APU our admins are faced with:

    	$ dmesg | grep -c "gpio-keys-polled gpio-keys-polled: unable to claim gpio 0, err=-517"
    	261

    Such a message always appears when e.g. a new USB device is plugged in.

    Suppress this message which considerably clutters the kernel log for
    EPROBE_DEFER (i.e. -517).
