From: Benoit Cousson <benoit.cousson@xxxxxxxxxx>
without that hwmod data, USB3 will not in OMAP5 boards.
While at that, also fix DTS data to pass reg property,
otherwise driver won't probe.

tested on OMAP5 uEVM. Gets rid of a data abort when USB3
is enabled. There still some other patches missing to get
USB3 working out of the box, but that's on Palmas and will
come as soon as I get those ready.
This is already on step forward.
