On Marvell Armada 3700 SoCs there are two USB2 UTMI PHYs. They are
both very similar but only one has OTG/charging capabilities.
Because there are USB host registers and PHY registers mixed in a
single area, a system controller is also created and referenced from
both the USB host node and the PHY node.
