VIA/WonderMedia SoC's have a chip ID register inside their system
configuration controller space, which can be used to identify
appropriate hardware quirks at runtime. Add binding for it.

+  versions of on-chip IP blocks having their own peculiarities which may or
+  may not be captured by their respective DT compatible strings

My bot found errors running 'make dt_binding_check' on your patch:

yamllint warnings/errors:

dtschema/dtc warnings/errors:
/builds/robherring/dt-review-ci/linux/Documentation/devicetree/bindings/hwinfo/via,vt8500-scc-id.yaml: $id: Cannot determine base path from $id, relative path/filename doesn't match actual path or filename
 	 $id: http://devicetree.org/schemas/soc/vt8500/via,vt8500-scc-id.yaml
 	file: /builds/robherring/dt-review-ci/linux/Documentation/devicetree/bindings/hwinfo/via,vt8500-scc-id.yaml

doc reference errors (make refcheckdocs):

See https://patchwork.ozlabs.org/project/devicetree-bindings/patch/20250503-wmt-soc-driver-v2-1-8c774ad84d47@gmail.com

The base for the series is generally the latest rc1. A different dependency
should be noted in *this* patch.

If you already ran 'make dt_binding_check' and didn't see the above
error(s), then make sure 'yamllint' is installed and dt-schema is up to
date:

pip3 install dtschema --upgrade

Please check and re-submit after running the above command yourself. Note
that DT_SCHEMA_FILES can be set to your schema file to speed up checking
your schema. However, it must be unset to test all examples with your schema.
