Invoke enable_usb_clocks during board_usb_init and disable_usb_clocks
during board_usb_exit to enable and disable clocks respectively.

Modifications:
* Enable USB clocks in the OMAP version of the function
  board_usb_init.
* Disable USB clocks in the OMAP version of the function
  board_usb_cleanup.
