[OpenWrt-Devel] [PATCH 1/2] ar71xx: flag FritzBox 4020 buttons as active low

[David Bauer]

Buttons of AVM FritzBox 4020 are incorrectly flagged as active high.

This was an oversight as RFKill button was working as expected even
with incorrectly flagged GPIO.

This commit should also be applied to the openwrt-18.06 branch as the
issue is also present there.
