    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.
