Bug description:
[Impact]
Enabling CL1 (Controller Low Power) states during discovery of existing
tunnels established by the system firmware can interfere with the operation of
those tunnels.
The DisplayPort tunnel establishment timeout of 1.5 seconds can be
insufficient for some docking stations, leading to blank displays.
[Fix]
CL1 states are now not enabled during discovery of existing tunnels. The TMU
settings also remain unchanged.
The timeout is increased to 3 seconds to allow more time for the DisplayPort
connection manager handshake, fixing the issue of displays remaining blank.
[Test Cases]
1. plug docking station on the host
2. bring up the host and get into desktop.
3. flip docking station's cable.
4. check if the external monitor works well
[Where problems could occur]
Low, If the handshake actually requires even more than 3 seconds in some
cases, the timeout may still need to be increased further.
[Misc]
Jammy needs more patches to enable the thunderbolt CLx and the SRU will be a
huge,
so skip Jammy.
