Subject: [PATCH 2/2] ARM: dts: imx6dl-yapp4: Model the RGB LED as a single multi-led part
Describe the RGB LED indicator according to the reality - it is a single
part containing all the three R,G and B LEDs in one package.
With this description the chan-name property becomes useless, remove it.
issue: HWOS-816
