ARM: mvebu: ensure the mdio node has a clock reference on Armada 38x
The mvmdio driver accesses some register of the Ethernet unit. It
therefore takes a reference and enables a clock. However, on Armada
38x, no clock specification was given in the Device Tree, which leads
the mvmdio driver to fail when being used as a module and loaded
before the mvneta driver: it tries to access a register from a
hardware unit that isn't clocked.
