Well this was a mess to figure out.
The only fix I can figure out here is to remove the
depends on LEDS_CLASS_MULTI_COLOR || !LEDS_CLASS_MULTI_COLOR
from each child device and add
select LEDS_CLASS_MULTI_COLOR
to the LP55XX_COMMON
This way the Multi color framework will inherit the symbol that was set
by the COMMON flag which is inherited by majority from the child flags.
