As found in the Pixel 3a, the Snapdragon 670 has a camera subsystem with
3 CSIDs and 3 VFEs (including 1 VFE lite). Add this camera subsystem to
the bindings.

Adapted from SC8280XP camera subsystem.

doc reference errors (make refcheckdocs):

See https://patchwork.ozlabs.org/project/devicetree-bindings/patch/20240813230037.84004-10-mailingradian@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.
