[PATCH] ARM: dts: rockchip: add the leds control for kylin board

[Caesar Wang]

As the kylin schematic drawing, add the needed work led for
kylin board.

Run:
ucho 0 > /sys/class/leds/kylin:red:led/brightness
echo 1 > /sys/class/leds/kylin:red:led/brightness

The led can be normall on/off on kylin board.
