OK. I've started working on this. I am looking at using struct usb_phy, 
however, enum usb_phy_type only has USB_PHY_TYPE_UNDEFINED, 
USB_PHY_TYPE_USB2, and USB_PHY_TYPE_USB3. Would it be acceptable to use 
USB_PHY_TYPE_UNDEFINED for the ohci since it is USB 1.1? Or perhaps I 
should use the more generic struct phy for that one?
