[PATCH v2] ARM: dts: rockchip: Adding LEDs handling via leds-gpio for the Radxa Rock2 Square

[Romain Perier <romain.perier-Re5JQEeQqe8AvxtiuMwx3w@public.gmane.org>]

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.

Signed-off-by: Romain Perier <romain.perier-Re5JQEeQqe8AvxtiuMwx3w@public.gmane.org>

- Changed labels according to what is defined in the schematics
- Added a long commit message describing this patch in details
