remoteproc: imx_rproc: Add support for System Manager LMM API

i.MX95 features a Cortex-M33 core, six Cortex-A55 cores, and
one Cortex-M7 core. The System Control Management Interface(SCMI)
firmware runs on the M33 core. The i.MX95 SCMI firmware named System
Manager(SM) includes vendor extension protocols, Logical Machine
Management(LMM) protocol and CPU protocol and etc.

Depending on SM configuration, M7 can be used as follows:
 (1) M7 in a separate Logical Machine (LM) from A55 cores, that Linux
     can't control
 (2) M7 in a separate LM from A55 cores that Linux can control using LMM
     protocol.
 (3) M7 runs in same Logical Machine as A55 cores, so Linux can control it
     using CPU protocol

So extend the driver to using LMM and CPU protocol to manage the M7 core.
 - Compare linux LM ID(got using scmi_imx_lmm_info) and M7 LM ID(the ID
   is fixed as 1 in SM firmware if M7 is in a separate LM),
   if Linux LM ID is not same as M7 LM ID(linux and M7 in same LM), use
   LMM protocol to start/stop. CPU protocol support will be added in the
   following patch. Whether using CPU or LMM protocol to start/stop, the
   M7 status detection could use CPU protocol to detect started or not. So
   in imx_rproc_detect_mode, use scmi_imx_cpu_started to check the
   status of M7.
 - For above case (1) and (2), Use SCMI_IMX_LMM_POWER_ON to detect whether
   the M7 LM is under control of A55 LM.
 - For above case , after using SCMI_IMX_LMM_POWER_ON to check
   permission, SCMI_IMX_LMM_SHUTDOWN API should be called to shutdown
   the M7 LM to save power only when M7 LM is going to be started by
   remoteproc framework. Otherwise bypass SCMI_IMX_LMM_SHUTDOWN API if
   M7 LM is started before booting Linux.

Current setup relies on pre-Linux software(U-Boot) to do M7 TCM ECC
initialization. In future, we could add the support in Linux to decouple
U-Boot and Linux.
