    libpayload: EHCI: Support root-hub TT feature
    
    If EHCI controller has TT (Transaction Translator) support in
    root-hub, then we need to keep control over this controller when
    USB keyboard (low-speed device) is connected to root-hub port.
    
    Need to add "CONFIG_LP_USB_EHCI_HOSTPC_ROOT_HUB_TT=y" to config file
    (e.g. payloads/libpayload/configs/config.nyan_big) to support this
    feature.
    
    BUG=chrome-os-partner:32355
    TEST=Tested on nyan_big platform.
    Press ESC+REFRESH+POWER keys on internal keyboard to power up.
    Press Left Arrow or Right Arrow on USB keyboard to switch between
    "English" and "Default Locale" in coreboot UI. Or unplug and plug
    in device and try again.
    Root hub <- low-speed USB keyboard
    Root hub <- full-speed hub <- low-speed USB keyboard
    Root hub <- high-speed hub <- low-speed USB keyboard
