Trim it a bit...

From schema: Documentation/devicetree/bindings/timer/ingenic,tcu.yaml

You need to explain this. You're changing the effective compatible of
the device and doing so based only on schema warning does not look
enough. Please write real reason instead of this fat warning, e.g. that
both devices are actually compatible and this has no real effect except
schema checks.

Well, if the schema says that it should use a particular fallback string, then that's what the DTS should use, right?

If making the DTS schema-compliant causes breakages, then that means the schema is wrong and should be fixed.
