thunderbolt: Fixes for v6.7-rc3

This includes following USB4/Thunderbolt fixes for v6.7-rc3:

  - Fix a lane bonding issue on ASMedia USB4 device
  - Send uevents when link is switched to asymmetric or symmetric
  - Only add device router DP IN adapters to the head of resource list
    to avoid issues during system resume.

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