OMAP3xxx: hwmod data: Add USBOTG

OMAP3 hwmod data structures are populated for USBOTG with base address,
L3 and L4 interface clocks, IRQs and sysconfig register details.
This is applicable for OMAP3430 amd OMAP3630.

As per OMAP USBOTG specification, need to configure the USBOTG
to smart idle/standby or no idle/standby during data transfer and
force idle/standby when not in use to support retention and offmode.
By setting HWMOD_SWSUP_SIDLE and HWMOD_SWSUP_MSTANDBY flags, framework
will take care of configuring to no idle/standby when module is enabled
and force idle/standby when idled.
