thunderbolt: Disable lane 1 for XDomain connection

Browse source

USB4 spec mandates that the lane 1 should be disabled if lanes are not
bonded. For host-to-host connections (XDomain) we don't support lane
bonding so in order to be compatible with the spec, disable lane 1 when
another host is connected.
