Add basic device tree support for the Axis ARTPEC-9 SoC
which contains 6-core Cortex-A55 CPU and other several IPs.
This SoC is an Axis-designed chipset used in surveillance camera products.

This ARTPEC-9 SoC has a variety of Samsung-specific IP blocks and
Axis-specific IP blocks and SoC is manufactured by Samsung Foundry.

This patch series includes below changes:
- Bindings document update for ARTPEC-9 board (patch #1)
- Device tree for ARTPEC-9 board (patch #2 and #3)

The patch series has been tested on the ARTPEC-9 EVB with
Linux Samsung SoC tree (for-next branch) and intended
to be merged via the `arm-soc` tree.

Pinctrl and UART DT-bindings are present in another patches which are listed below:

Changes in v2:
- Decouple the device tree related patches which was present in v1 (Patch #5 to #7)
  Device tree related patches will be sent in separate series.

My bot found new DTB warnings on the .dts files added or changed in this
series.

Some warnings may be from an existing SoC .dtsi. Or perhaps the warnings
are fixed by another series. Ultimately, it is up to the platform
maintainer whether these warnings are acceptable or not. No need to reply
unless the platform maintainer has comments.

If you already ran DT checks and didn't see these error(s), then
make sure dt-schema is up to date:

  pip3 install dtschema --upgrade


This patch series was applied (using b4) to base:
 Base: attempting to guess base-commit...
 Base: tags/next-20251119 (exact match)
 Base: tags/next-20251119 (use --merge-base to override)

If this is not the correct base, please add 'base-commit' tag
(or use b4 which does this automatically)
