thunderbolt: Do not touch CL state configuration during discovery

If the boot firmware has already established tunnels, especially ones
that have special requirements from the link such as DisplayPort, we
should not blindly enable CL states (nor change the TMU configuration).
Otherwise the existing tunnels may not work as expected.

For this reason, skip the CL state enabling when we go over the existing
topology. This will also keep the TMU settings untouched because we do
not change the TMU configuration when CL states are not enabled.
