arm64: dts: allwinner: add snps,dwmac-mdio compatible to emac/mdio

montjoie · mripard · commit 16416084e06e · 2017-10-31T14:32:08.000+01:00
stmmac bindings docs said that its mdio node must have
compatible = "snps,dwmac-mdio";
Since dwmac-sun8i does not have any good reasons to not doing it, all
their MDIO node must have it.
