I was floundering about stating the LED purpose, because vendor didn't
explicitly
assign function for them and even the enclosure of the device lacks any marking.
The only markings are on PCB which nodes are named from. That's why I kept the
label property. I'll keep this patch lingering until conclusion which available
function to use.

I'll will add the migration, need to decide which function to use, from the ones
available.
