Jim Lin 654cf9c2d8 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
