    lantiq/xrx200: fix WLAN button actions for Fritzbox 3370
    
    The WLAN button actions are reversed, i.e. pressing the button emits a
    'released' action, and vice versa.
    This can easily be checked by adding
    logger -t button_action "$BUTTON $ACTION"
    as the second line of /etc/rc.button/rfkill, and using logread to read
    the events (assuming the preceding patch has been applied).
    Defining the GPIO as ACTIVE_LOW corrects this behavior.
