[PATCH v4 9/9] ARM: tegra: venice2: Add xHCI support

[Andrew Bresticker]

Assign ports previously owned by the EHCI controllers to the xHCI
controller.  There are two external USB ports (UTMI ports 0/2 and
USB3 ports 0/1) and an internal USB port (UTMI port 1).  PCIe lanes
0 and 1 are used by the USB3 ports.
