The XXV Ethernet IP integrates a 10G/25G Ethernet MAC with an in-core
PCS/PMA driving a high-speed serial transceiver. Extend the existing
xlnx,axi-ethernet binding to describe it.
Add the "xlnx,xxv-ethernet-1.0" compatible and make the resource
requirements conditional based on the XXV compatible string:
- "dmas", "dma-names", and "phy-mode" are required.
- Interrupt properties are not required as it does not have a dedicated
Ethernet core interrupt.
- "phy-handle" is not required as it has internal PCS and PMA.
- Add the 10gbase-r and 25gbase-r phy-mode values used by XXV.
Annotate the existing compatibles, generalise the title to cover both
variants, and add an example node for XXV.
Define properties at top level per binding style and use if/then to
constrain requirements and phy-mode per compatible. Forbid 1G-only and
unused ethernet-controller properties on XXV nodes.

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.
