Subject: [PATCH v3 2/2] arm64: dts: allwinner: pinephone: add multicolor LED node

The red, green, and blue LEDs currently in the device tree represent a
single RGB LED on the front of the PinePhone.

Signed-off-by: Aren Moynihan <aren@...cevolution.org>

Changes in v3:
 - add function property back to individual LED nodes to minimize
   breaking changes

Changes in v2:
 - remove function property from individual LED nodes
