thunderbolt: Take CL states into account when waiting for link to come up

Browse source

If CL states are enabled for the link it may be in these states too when
reading the lane adapter state but it will enter CL0 as soon as there is
traffic in the high-speed lanes. Upon discovery we want to make sure
that is accounted as the link being up, otherwise we end up tearing down
the topology with no good reason.
