ARM: dts: rockchip: Add LEDs via gpio-leds for Radxa Rock2 Square

Describe the two user-controllable LEDs on Rock2 Square boards.
All information have been retrieved from the schematics and the vendor
devicetree. The default-triggers mimic the behaviour of the vendor-kernel to
keep functionalities in sync.
