Currently it doesn't matter where the mdio nodes are placed, but with power management support (i.e. when sleep = <> properties will take effect), mdio nodes placement will become important: mdio controller is a part of the ethernet block, so the mdio nodes should be placed correctly. Otherwise we may wrongly assume that MDIO controllers are available during sleep.
