Subject: [PATCH] mpc85xx: update lp5521 led-controller node for 5.10

The tricolor LED which is controlled by a lp5521 needed
some maintenance as the driver failed to load in the
current v5.10 image:
| lp5521: probe of 0-0032 failed with error -22

This is because the device-tree needed to be updated
to match the latest led coloring and function trends.

 - removed the device name from the label
 - added color/function properties
 - added required reg and cells properties

For reference a disabled multicolor/RGB is added since this
reflects the real hardware. Unfortunately, the multicolor
sysfs interface isn't supported by yet.
