This is just a board configuration and there is absolutely no need to document
this in common LED binding. But if your intention is to document the missing
triggers, then you should look at the patch I submitted long ago.

Maybe I should resubmit it again in YAML format. (thanks for reminding me :P)

Thanks,
Mani
