[00/14] TGL TC enabling

Message

This is all the patches required to have TC alt-mode working on TGL, no TBT or legacy support intented here but much of the work here will help those.

The dkl pll calculation is not 100% ready, so it is using the hardcoded table provided but even with this table it results in a port_clock state mismatch when running at 5.4Ghz.
Also I'm still debugging why enable clock gating after link training complete breaks all the following trainings.
All of above is noted in the respective commit message.

Other than the above the series is pretty much ready for reviews and testing.
Make sure you have firmware of TC retimers updated.
