Bug description:
[SRU Justification]
[Impact]
The Thunderbolt controller is integrated into the Ice Lake CPU itself
and requires special flows to power it on and off using force power bit
in NHI VSEC registers. Currently this is not supported until v5.4-rc1.
[Fix]
Commit 3cdb9446a117 "thunderbolt: Add support for Intel Ice Lake" along
with all the prerequisites should be backported to enable thunderbolt.
[Test Case]
Tested on two Dell XPS platforms with ICL-U and thunderbolt support.
[Regression Risk]
Medium. While v5.4 is still under development and there is already an
known issue about suspend/resume on ICL platforms with thunderbolt
enabled, it is definitely going to have follow-ups for this backport, as
well as more regression tests on previous systems before landed.
