This series adds USB device support for Tegra234. 3/5 patches were
originally part of the series to add both USB host and device support
for Tegra234 [0]. However, the series was getting quite large and so I
have split this into a separate series but calling it 'V4' to indicate
that this is not completely new either.

I have added two more patches in this version to fix DMA coherency for
Tegra194.
