ramips: add led_source for Asus RT-AC1200 devices
this adds the mediatek,led_source dts binding for
Asus RT-AC1200 devices' dtsi, for correct switch LED
behavior.
The dts-binding is introduced in commit:
65dc9e0980255b15402c45b840f239b85be59b3d
Without this, we only have constantly very fast
blinking LEDs, which don't react on any traffic or
LAN events at all.
