[PATCH v3 9/9] arm64: marvell: dts: add xmdio nodes for 7k/8k

[Antoine Tenart <antoine.tenart@free-electrons.com>]

Add the description of the xMDIO bus for the Marvell Armada 7k and
Marvell Armada 8k; for both CP110 slave and master. This bus is found
on Marvell Ethernet controllers and provides an interface with the
xMDIO bus.

@Dave: this patch should go through the mvebu tree as asked by Gregory, thanks!
