USB_OHCI_LITTLE_ENDIAN and USB_OHCI_BIG_ENDIAN are useful and I
don't see anyone wanting to remove them.  However, if all of the
chips supported by the ohci-ppc-of driver are big-endian, then
USB_OHCI_HCD_PPC_OF_LE and USB_OHCI_HCD_PPC_OF_BE are not needed.
Just select USB_OHCI_BIG_ENDIAN when the ohci-ppc-of driver is
selected, in the same way that we always select USB_OHCI_LITTLE_ENDIAN
when the ohci-pci driver is selected.
