    renesas_usbhs driver can play role as both Host and Gadget.
    In case of Gadget, it requires not only renesas_usbhs
    but also usb gadget module (like g_ether).
    So, renesas_usbhs driver calls usb_add_gadget_udc() on probe time.
    
    Because of this behavior,
    Host port plays also Gadget role if kernel has both Host/Gadget support.
    
    In mackerel case, from 0ada2da5
    (ARM: mach-shmobile: mackerel: use renesas_usbhs instead of r8a66597_hcd)
    usb0 plays Gadget role, and usb1 plays Host role,
    and current mackerel board probes as usb1 -> usb0.
    Thus, 1st installed usb gadget module (like g_ether) will be
    assigned to usb1 (= usb Host port), and 2nd module to usb0 (= usb Gadget port).
    It is very confusable for user.
    This patch fixup usb modes probing order as usb0 -> usb1.
