Turn Sony motion controller into RGB led

From: Pavel Machek
Date: Thu Apr 09 2015 - 17:25:44 EST

Hi!

I did not yet figure out how to get sensor data from the controller,
but it works rather well as a RGB led.

And yes, this probably would need some more cleanup, but I'm out of
time now. Perhaps someone else can help...

BTW what happened to the __u8->u8 conversion patch? That should go in AFAICT.
