include: dwc3-omap-uboot: add a structure for populating dwc3-omap platform data

Added a structure to populate dwc3 omap platform data. The board file should
populate these platform data before invoking dwc3 omap driver.

This will be removed once dwc3-omap driver is adapted to use the driver model.
