net: mdio-uclass: name MDIO according to device-name property if preset
Use the optional property device-name to name the MDIO bus. This works around limitations with using the DT node name on devices such as Armada-8040, which integrates two cp100 cores, both featuring MDIOs at the same relative offsets and with the same DT node names. The concept was originally proposed by Marvell as a custom property called mdio-name specific to Marvell driver. This patch uses the more generic property device-name and moves this into MDIO class code so other can use it as well.
