Why? It would make sense if there were devices using this controller
having other configuration, but on Omnia, all LEDs are RGB.
Also, if I do this, should I also make the driver check in the probe
function whether the per-channel child nodes are correct? Eg. if they
are always three: one for red, one for green and one for blue? Or
should the driver ignore this and only the device tree binding specify
it?
Because the way the driver is written now, it only registers
multi-color RGB LEDs.
