I'm not convinced we want to support multi-LED framework.

If 3 GPIOs control one physical LED, yes, we want to support that.

If the goal is to create one virtual LED from 4 physical LEDs arranged
side by side... I'd say... deal with the complexity in userland. It is
not critical to do it in kernel.
