Remove DECLARE_GLOBAL_DATA_PTR from files where gd is not used, and
drop the unnecessary inclusion of asm/global_data.h.

Headers should be included directly by the files that need them,
rather than indirectly via global_data.h.

i.MX95 uses System Manager(sm) API to start/stop logical machine or cpu.
There are two modes:
 M7 in a dedicated logical machine, use LMM API
 M7 and A55 in same logical machine, use CPU API

Extend the driver to using LMM and CPU protocol to manage the M7 core:
 - Detect using LMM or CPU API in probe using API scmi_imx_lmm_info().
 - 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. 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_is_running, use scmi_imx_cpu_started to
   check the status of M7.
 - For above case (2), Use scmi_imx_lmm_power_boot 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.
 - Add a new ops imx_rproc_ops_sm.

Add a new flag ATT_ECC which indicates the memory region needs ECC
initialization. If the flag is set, clearing the whole memory region to
initialize ECC. If ECC is not initialized, remote core will crash if
directly access the area.

Add is_running callback to query the R5F core halt status via the
TI-SCI processor control API. This allows the remoteproc framework
to determine whether the R5F core is currently runnin.

The core is considered running when the PROC_BOOT_CTRL_FLAG_R5_CORE_HALT
bit is not set in the control flags.

After ti_secure_image_post_process() authenticates the image, it may
relocate it to a different memory location and update image_addr to
point to the verified image.

However, rproc_elf_load_image() and rproc_elf_get_boot_addr() were
still using the original "addr" parameter, potentially operating on
the unverified or stale image location instead of the authenticated
image.

Use image_addr (cast to ulong to match function signatures) after
authentication to ensure all operations work with the verified image.

When compiling for R5 core with CONFIG_REMOTEPROC_TI_K3_R5F,
passing 'size' (ulong) to ti_secure_image_post_process() caused
a type mismatch compiler error.

On platforms where ulong and size_t differ in size, directly
casting could lead to out-of-bounds memory access. Fix by
introducing a size_t temporary variable, passing it to the
function, and writing back the potentially modified value for
use in subsequent calls.

Introduce remote processor configuration for the i.MX93 Cortex-M33 core.

This patch adds:
- Address translation table (ATT) for i.MX93, including TCM
  (secure and non-secure) and DDR regions.
- A new device configuration structure `imx_rproc_cfg_imx93` using SMC
  method and ARM SMC ops.
- Device tree match entry for "fsl,imx93-cm33"

This enables remoteproc framework to properly initialize and manage the
Cortex-M33 core on i.MX93 platforms.
