We typically only add those when they are really needed. These are
technically harmless because without a reference, DTC won't actually
create a phandle property, but dangling labels are the kind of thing
that some janitor may at some point want to remove with some scripts,
so I'm hesitant to apply this because it'll likely cause churn in the
future.
