[PATCH] rpmsg: glink-smem: Name the edge based on parent remoteproc

[Bjorn Andersson]

Naming the glink edge device on the parent of_node short name causes
collisions when multiple remoteproc instances with only different unit
address are described on the platform_bus in DeviceTree.

Base the edge's name on the parent remoteproc's name instead, to ensure
that it's unique.
