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.

In the current implementation of SMD this value goes straight into an
sysfs attribute that we can use when writing udev rules and for the DIAG
implementation to pair up channels related to the same remoteproc. This
adds the equivalent information for glink-backed channels.


I'm therefor in favor of picking this patch.

Please add these details to the commit log. Just writing what the patch
is doing isn't very helpful.
