da8xx/hawkboard: Add support for ohci host controller
Also enable the ohci port on hawkboard. These additions result in an increased u-boot size -- adjust the same accordingly in the board's config. Move the usb header for da8xx platforms under arch-davinci. Signed-off-by: Sughosh Ganu <urwithsughosh@gmail.com>
