thunderbolt: Changes for v5.10 merge window

This includes following Thunderbolt/USB4 changes for v5.10 merge window:

  * A couple of optimizations around Tiger Lake force power logic and
    NHI (Native Host Interface) LC (Link Controller) mailbox command
    processing

  * Power management improvements for Software Connection Manager

  * Debugfs support

  * Allow KUnit tests to be enabled also when Thunderbolt driver is
    configured as module.

  * Few minor cleanups and fixes

All these have been in linux-next with no reported issues.
