Add a label property to identify the edge this node represents.

Why does a user need to know this?

We have multiple remoteproc instances, each one having one or more
associated SMD or GLINK links (this node), exposing logical
communication channels. Some of these logical channels are exposed to
user space and we need a way to distinguish them there.

They should have some sort of discoverable property. There must be
some reason why you need a specific channel. I think of label as being
a sticker or silkscreen on a device which doesn't seem to be the case
here. This seems more like wanting fixed device numbering like disks
and I assume you know the position on fixed device numbers.
