Subject: [PATCH V5 12/12] ARM: tegra: venice2: Add xHCI support

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.

Changes from v4:
 - Updated regulator and pinconfig properties.
No changes from v3.
Changes from v2:
 - Updated VBUS power supply names.
Changes from v1:
 - Updated USB power supplies.
