thunderbolt: Changes for v6.7 merge window

This includes following USB4/Thunderbolt changes for the v6.7 merge window:

- Configure asymmetric link if the DisplayPort bandwidth requires so
- Enable path power management packet support for USB4 v2 routers
- Make the bandwidth reservations to follow the USB4 v2 connection manager guide suggestions
- DisplayPort tunneling improvements
- Small cleanups and improvements around the driver.

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