mb/google/volteer: disable TBT if no USB4 hardware available

Implement mainboard_silicon_init_params() to allow for disabling of
TBT root ports if the device does not have usb4 hardware.

Add code to mainboard_memory_init_params() to disable memory-related
settings associated with TBT in cases where no usb4 is available.
