I am unclear of the motivation for using the label property when
its value is so similar to the name of the node.

The reason I noticed this is that it appears to differ from led nodes
for other Renesas ARM SoCs. I'm not opposed to using the label property
if there is some value to it. But I would prefer to use it consistently.
And I'd prefer not to add it to all the other SoCs unless there is a reason
to.
