Add devicetree bindings for ad7405/adum770x family.
Signed-off-by: Pop Ioan Daniel <pop.ioan-daniel@analog.com>
---
changes in v2:
- remove #address-cells and #size-cells
- add additionalProperties: false instead of unevaluatedProperties: false
- remove #include <dt-bindings/interrupt-controller/irq.h>
because it's not used
- add new line at the end of the file
- add mantainer

See https://patchwork.ozlabs.org/project/devicetree-bindings/patch/20250508123107.3797042-4-pop.ioan-daniel@analog.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.

These last three devices have the same match data, why is a fallback
compatible not appropriate? (Please list the reason in your commit
message).
