ec/google/chromeec: Add CFR option for RGB keyboard boot color

Browse source 
Add ec_rgb_kb_color CFR option to select RGB keyboard color at
boot. Suppress regular keyboard backlight option when RGB keyboard
is present, as they are mutually exclusive.

TEST=build/boot google/mithrax, verify RGB keyboard option enabled,
all colors able to be set at boot.
