thunderbolt: Add support for Intel Alder Lake
[ Upstream commit 135794868ad83d0327cdd78df469e118f1fe7cc4 ]
Alder Lake has the same integrated Thunderbolt/USB4 controller as
Intel Tiger Lake. By default it is still using firmware based connection
manager so we can use most of the Tiger Lake flows.
Add the Alder Lake PCI IDs to the driver list of supported devices.
