dt-bindings: remoteproc: glink-rpm-edge: Use "glink-edge" as node name

Semantically glink-edge and glink-rpm-edge are similar: Both describe
the communication channels to a remote processor. The RPM glink-edge is
a special case that needs slightly different properties but otherwise
it is used exactly the same.

To improve consistency use the same "glink-edge" node name also for
glink-rpm-edge. Drop the $nodename from qcom,glink-edge.yaml to avoid
matching the wrong schema. qcom,glink-edge.yaml is always referenced
explicitly from other schemas. This will already ensure that the nodes
are being checked, so it's not necessary to bind to all nodes named
"glink-edge".
