on-board USB 2.0 hub, FE1.1s, has Transaction Translator which can
handle USB 1.x devices via "usb_host0_ehci". so we can omit
"usb_host0_ohci" and make boot faster (a little).

The OHCI is in use when the direct connect device is USB1.1; and if the
board
connect with usb2.0 hub, then only EHCI is working and OHCI has no use.
