ipq806x: Add USB support
This patch adds code to initialize the two DWC3 USB host controllers and
their associated PHYs to the IPQ806x SoC (closely imitating the existing
DWC3 implementation for Exynos5), and uses them to initialize USB on the
Storm mainboard.
BUG=chrome-os-partner:29375
TEST=Hack up netboot to get around missing SPI flash, load a file over
TFTP. Hack a storage read into the storage attach function, dump the
data and confirm that it looks right. Enable USB debugging and confirm
3.0 devices get enumerated at SuperSpeed (mostly).
