Convert adi,ssm2602 binding to DT schema

The original adi,ssm2602.txt contains bindings for 3 devices
SSM2602, SSM2603 and SSM2604. Since they share something
in common. So I created one single yaml and name it 260x instead.
Let me know if you think it should be done in another way.

It passed dt_binding_check and dtbs_check.

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

yamllint warnings/errors:

dtschema/dtc warnings/errors:

See https://patchwork.ozlabs.org/project/devicetree-bindings/patch/20240511214739.242950-1-shenxiaxi26@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.
