    libpayload: add controller type in usbdev_hc
    
    Add controller type (UHCI, OHCI, EHCI or XHCI)
    into usbdev_hc (hci_t) struct, so now we know
    which type selected controller have. It needed
    to access controller specific data, if access
    usb tree outside of libpayload (e.g. in payload
    intself)
