thunderbolt: Add KUnit test for devices with no DisplayPort adapters (2022-05-12 09:22:36 +0300)

----------------------------------------------------------------
thunderbolt: Changes for v5.19 merge window

This includes following Thunderbolt/USB4 changes for the v5.19 merge window:

* Improvements for Thunderbolt 1 DisplayPort tunneling
* Link USB4 ports to their USB Type-C connectors
* Lane bonding support for host-to-host (XDomain) connections
* Buffer allocation improvement for devices with no DisplayPort adapters
* Few cleanups and minor fixes.

All these have been in linux-next with no reported issues except that there is a minor merge conflict with the kunit-next tree because one of the commits touches the driver KUnit tests.
