[PATCH v6 06/11] ARM: dts: sunxi: h3/h5: represent the mdio switch used by sun8i-h3-emac

[Corentin Labbe <clabbe.montjoie@gmail.com>]

Since dwmac-sun8i could use either an integrated PHY or an external PHY
(which could be at same MDIO address), we need to represent this selection
by a MDIO switch.
