[PATCH net-next v2] dt-bindings: net: aspeed: add AST2700 MDIO compatible

[PATCH net-next v2] dt-bindings: net: aspeed: add AST2700 MDIO compatible

[Jacky Chou]

Add "aspeed,ast2700-mdio" compatible to the binding schema with a fallback
to "aspeed,ast2600-mdio".

Although the MDIO controller on AST2700 is functionally the same as the
one on AST2600, it's good practice to add a SoC-specific compatible for
new silicon. This allows future driver updates to handle any 2700-specific
integration issues without requiring devicetree changes or complex
runtime detection logic.

For now, the driver continues to bind via the existing
"aspeed,ast2600-mdio" compatible, so no driver changes are needed.
