ARM: dts: imx6dl-yapp4: Fix lp5562 LED driver probe

stable inclusion
from stable-5.10.73
commit ac06fe40e8896c96786b47857ddc50738a103f6e
bugzilla: 182983 https://gitee.com/openeuler/kernel/issues/I4I3M0

Reference: https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git/commit/?id=ac06fe40e8896c96786b47857ddc50738a103f6e

--------------------------------

commit 9b663b34 upstream.

Since the LED multicolor framework support was added in commit
92a81562 ("leds: lp55xx: Add multicolor framework support to lp55xx")
LEDs on this platform stopped working.

Author of the framework attempted to accommodate this DT to the
framework in commit b86d3d21 ("ARM: dts: imx6dl-yapp4: Add reg property
to the lp5562 channel node") but that is not sufficient. A color property
is now required even if the multicolor framework is not used, otherwise
the driver probe fails:

  lp5562: probe of 1-0030 failed with error -22

Add the color property to fix this.
