Subject: [PATCH] dt-bindings: net: snps,dwmac: Align mdio node in example with bindings

According to the bindings, the MDIO subnode should be called "mdio".
Update the example to match this.

For dwc-qos-ethernet-4.10, the Linux driver insists on "mdio".
For other devices, the Linux driver does not seem to care, and just
looks for subnodes that are compatible with "snps,dwmac-mdio":
https://elixir.bootlin.com/linux/v6.14.6/source/drivers/net/ethernet/stmicro/stmmac/stmmac_platform.c#L302

Lots of DTS files are using "mdio0" (copied from the example?).
