Subject: [PATCH 5/8] ARM: mvebu: Add Device Tree description of xHCI hosts on Armada 38x

The Marvell Armada 38x SoCs contain two xHCI host. This commit adds
the Device Tree description of those interfaces at the SoC level, and
also enables the two USB3 ports on the Armada 385 DB platform and one
USB3 port on the Armada 385 RD platforms.
