OMAP2430: hwmod data: Add USBOTG

OMAP2430 hwmod data structures are populated with base address, L3 and L4
interface clocks, IRQs and sysconfig register details.

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 off-mode.
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 suspended.
