FROMLIST: arm64: dts: qcom: iq9: Introduce new memory map for qcs9100/qcs9075

SA8775P has a memory map which caters to the auto specific requirements.
QCS9100 & QCS9075 are its IOT variants (with marketing name as IQ9) which
inherit the memory map of SA8775P require a slightly different memory
map as compared to SA8775P auto parts.
This new memory map is 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 as part of firmware updates for IoT. The size and base address
have been updated for video PIL carveout compared to SA8775P since it is
being brought up for the first time on IoT boards. The base addresses
of the rest of the PIL carveouts have been updated to accommodate the
change in size of video since PIL regions are relocatable and their
functionality is not impacted due to this change. The size of camera
pil has also been increased without breaking any feature.

The size of trusted apps carveout has also been reduced since it is
sufficient to meet IoT requirements. Also, audio_mdf_mem & tz_ffi_mem
carveout and its corresponding scm reference has been removed as these
are not required for IoT parts.

Incorporate these changes in the updated memory map.
