Subject: [PATCH v5 3/7] dt-bindings: remoteproc: Add processor identifier property

Add the "st,proc-id" property allowing to identify the remote processor.
This ID is used to define an unique ID, common between Linux, U-boot and
OP-TEE to identify a coprocessor.
This ID will be used in request to OP-TEE remoteproc Trusted Application
to specify the remote processor.
