arm64: dts: mediatek: mt7981b-openwrt-one: Enable software leds

Browse Source 
The openwrt has 3 status leds at the front:
* red: Used as failsafe led by openwrt
* white: Used as boot led by openwrt
* green: Used as running/upgrade led by openwrt

On the back each RJ45 jack has the typical amber/green leds. For the WAN
jack this is hardware controlled by the phy, for LAN these are under
software control and enabled by this patch.
