thunderbolt: Disable CL states for the Anker Prime TB5 dock
The Anker Prime TB5 dock identifies itself in the DROM as 01ea:83b5.
Its router config space is an Intel Barlow Ridge 80G hub (8087:5786).
The upstream lane adapter advertises CL0s, CL1, and CL2. With CLx left
enabled, TMU uni-directional LowRes setup fails with -ENOTCONN, the USB3
and DisplayPort tunnels are aborted, and the router reconnects in a loop.
Loading thunderbolt with clx=0 keeps the link up on this machine.
Match the DROM id together with the Barlow Ridge hub id and disable CL
states for this dock only. QUIRK_NO_CLX takes the same early-out as the
module parameter, without disabling CLx for every other router.
