thunderbolt: Changes for v6.18 merge window

This includes following USB4/Thunderbolt changes for the v6.18 merge
window:

  - HMAC hashing improvements
  - Switch to use Linux Foundation IDs for XDomain discovery
  - Use is_pciehp instead of is_hotplug_bridge
  - Fixes for various kernel-doc issues
  - Fix use-after-free in DP tunneling error path.

I'm sending the UAF fix with this pull request because it came quite
late and I would like to give it some exposure before it lands the
mainline.

All these except the UAF fix have been in linux-next with no reported
issues.
