ARM: tegra: Harmony: enable ULPI USB port

The ULPI port is routed onto pins on the mini PCI Express connector. A
standard breakout board may be used to access the port.

* Add required DT entries to configure the ULPI port.
* Setup up the ULPI pinmux in the board code.
* Enable multiple USB controller and ULPI support in the board config.
