coresight: replicator: Add new device id for static replicator

This patch adds a device id for the new static replicator compatible
string; it changes the driver name from "coresight-replicator" to
"coresight-static-replicator" as well.

This patch also gives warning when use the replicator obsolete DT
binding.
