[U-Boot] [PATCH v2 0/5] Tegra 2 USB ULPI series

With this series we are able to initialize USB controllers
using an external ULPI phy AKA USB2 on Tegra 2 devices.

This was tested to work on a Toradex Colibri T20 board,
where USB2 is used to access the ASIX ethernet chipset.
Testing was done with "tegra20: usb: rework set_host_mode" [1]
applied. I did not spot any regressions on the UTMI ports.

v2 incorporates all the review feedback I've got so far,
including now trying harder to enable VBus in all configurations.

Patch 3 is already in u-boot-usb and only provided as the ULPI
init code now depends on it.
Igor could you please take a look at Patch 4?

Patchset is based on top of u-boot-tegra/next
