arm64: dts: qcom: lemans: Update memory-map for IoT platforms 



The "automotive" memory map is the special case for the Lemans
configuration described by this dtsi, move it aside and use the IoT
memory map as the baseline.

Introduce "lemans-auto" as a derivative of "lemans" that retains the
old automotive memory map to support legacy use cases.

As part of the IoT memory map updates:
  - Introduce new carveouts for gunyah_md and pil_dtb. Adjust the size and
    base address of the PIL carveout to accommodate these changes.
  - Increase the size of the video/camera PIL carveout without affecting
    existing functionality.
  - Reduce the size of the trusted apps carveout to meet IoT-specific
    requirements.
  - Remove audio_mdf_mem, tz_ffi_mem, and their corresponding SCM references,
    as they are not required for IoT platforms.
