I hummed and harded about this case. The binding is there, documented
and in use. It comes from the times before we started pushing back on
vendor LED configuration methods. All this patch does is extend the
existing binding to another device of the same family. It seemed
unfair to reject it. The mess of a vendor proprietary binding exists,
and this does not make it worse.

For 88x3310 there is no president set, it should be done via Linux
LEDs.
