thunderbolt: Add support for enhanced uni-directional TMU mode
This is new TMU mode introduced with the USB4 v2. This mode is simpler
than the existing ones and allows all CL states as well. Enable this for
all links where both side routers are v2 and keep the existing
functionality for the v1 and earlier links.
Currently only support the MedRes rate. We can add the HiFi rate later
too if it turns out to be useful.
