----------------------------------------------------------------
thunderbolt: Changes for v5.2 merge window

This improves software connection manager on older Apple systems with
Thunderbolt 1 and 2 controller to support full PCIe daisy chains,
Display Port tunneling and P2P networking. There are also fixes for
potential NULL pointer dereferences at various places in the driver.
