This means ehci/ohci device registration happened compulsorily if Soc/platform calls r8a7778_init_late().
but, usb phy isn't registered without r8a7778_add_usb_phy_device().
The ohci/ehci resource will be used vainly if platform doesn't have USB
ohci/ehci and phy should be registered in same time/function.
