OMAP4: hwmod data: Add USBOTG
OMAP4 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 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.
