Bug description:
[Impact]
When a Thunderbolt monitor gets plugged to an AMD laptop for second time, the
Thunderbolt monitor remains blank.
[Fix]
Reinitialize TMU and perform proper Time Synchronization Handshake every time.
[Test]
The Thunderbolt monitor still has image after many replugging.
[Where problems could occur]
This change the flow on disabling TMU, which is responsible for time
synchronization, so behavior of Thunderbolt docking might be affected. Per my
limited test no issue has been observed.
