OMAP3: PM: reset USB OTG module on boot
FIXME: add USB OTG hwmod so this is not needed
Rather than simply setting force-idle mode on boot, do a reset of the
OTG module. This really ensures that any bootloader/bootstrap code
that leaves it active will not prevent future retention. After reset,
OTG module will be in force-idle, force-standby mode.
