SA8775P has a memory map which caters to the auto specific requirements. IOT boards (viz. QCS9100*, QCS9075*) which inherit the memory map of SA8775P require a slightly different memory map as compared to SA8775P auto parts. This dtsi describes the updated memory map applicable for all the IOT boards which inherit the initial SA8775P memory map. This is not applicable for non-IOT boards. Some new carveouts (viz. gunyah_md and a few pil dtb carveouts) have been introduced and the size and base addresses have been updated for a few of existing carveouts compared to SA8775P. Also, tz_ffi_mem carveout and its corresponding scm reference has been removed as it is not required for these boards. Incorporate these changes in the updated memory map.
