thunderbolt: Disable XDomain lane 1 only in software connection manager

commit 84ee211c83212f4d35b56e0603acdcc41f860f1b upstream.

When firmware connection manager is in use we should not touch the lane
adapter (well or any) configuration space so do this only when we know
that the software connection manager is active.
