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.

Pressing the 'WLAN' button should enable/disable wireless activity.
However, on the Fritzbox 3370 this doesn't have an effect.
This patch changes the mapping of the physical WLAN button, so a button
press will emit an action for the 'rfkill' key instead of 'wlan'.
Apparently, this is what stock OpenWRT expects, and also what is
implemented for most other devices.

Duplicate kernel 4.19 config and patches for kernel 5.4.
Duplicate the devicetree source files as well, they need kernel 5.4
specific adjustments.
