[00/20] thunderbolt: Initial USB4 v2 support

Message

Hi all,

This series adds initial support for the next USB4 version (USB4 v2) and
the Intel Barlow Ridge discrete controller. This includes support for
the 80G symmetric link, the necessary configuration needed to bring up
the router in v2 mode, adaptive TMU, PCIe extended encapsulation, and
CL2 low power link state. We will be sending the rest of the USB4 v2
support, including asymmetric 128/80G link support later on once this
one has settled.

The series is based on the "CLx and TMU rework" series I sent out
earlier this week:
