kernel: modules: add support for led-group-multicolor

This option enables support for monochrome LEDs that are grouped into multicolor
LEDs which is useful in the case where LEDs of different colors are physically
grouped in a single multi-color LED and driven by a controller that doesn't have
multi-color support.
