Subject: [PATCH] fbd-dev-led-multicolor: Support red, green, blue and white
 LED colors

Provide our own supports_color method to specify which colors are
actually implemented by the driver. RGB LEDs could provide different
colors as well such as orange, purple, etc. but those are not supported
yet.
