Subject: [PATCH 1/3] dt-bindings: remoteproc: fsl,imx-rproc: Add support
 for i.MX95

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

i.MX95 has a System Manager(SM) core runs the System Control Management
Interface(SCMI) firmware. Vendor extenions are implemented in the
firmware, Logical Machine Management(LMM) protocol to manage
Logical Machines and CPU protocol to manage cores. The documentation
could be found in file drivers/firmware/arm_scmi/vendors/imx/imx95.rst.

Add below to support i.MX95
 - compatible string for i.MX95 M7
 - fsl,lmm-id to indicate the LMM ID of M7 LM
 - fsl,cpu-id to indicate the CPU ID of M7
