[PATCH 05/11] remoteproc: imx_rproc: Add support for i.MX93 CM33

[Peng Fan (OSS)]

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

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.
