mb/google/volteer: Only enable TBT root ports if USB4 is supported

TBT ports should be disabled if the DB is a USB3 DB. It is assumed if
the DB doesn't support USB4 the platform as a whole should only be USB3
capable and TBT functionality on both ports should not be enabled.

BUG=NONE
BRANCH=NONE
TEST=Built coreboot and verified that TBT was disabled on platform with
USB3 DB and enabled on platform with USB4/TBT DB
