Add dedicated device tree node for RPM processor/subsystem

The RPM processor/subsystem is the only user of the /smd top-level
node. All other remote processors define their SMD channels/edges
in a "smd-edge" subnode inside the DT node of the remote processor.
Since the RPM has its own dedicated device tree node now as well,
deprecate using the dummy /smd node.
