From: Peng Fan <peng.fan@nxp.com>

Add i.MX SCMI Extension protocols bindings for:
- Logic Machine Management(LMM) Protocol
  intended for boot, shutdown, and reset of other logical machines (LM).
  It is usually used to allow one LM to manager another used as an offload
  or accelerator engine..
- CPU Protocol.
  allows an agent to start or stop a CPU. It is used to manage auxiliary
  CPUs in an LM (e.g. additional cores in an AP cluster).

Please add 'description' to these to say what the protocol is.
