Bug Description

[Impact]
Error message "ucsi_acpi USBC000:00: GET_CONEECTOR_STATUS failed (-110)"
can be found on many systems.

[Fix]
The main issue is that the PD firmware is unreliable, so use more
deterministic methods to make it reliable

[Test]
The error message is gone. Also tried to plug/unplug USB Type-C power
cord, and the status are always reported correctly.

[Where problems could occur]
This is quite a huge refactor, so regression can be expected. Only
target to unstable and latest OEM kernel to reduce risk we are taking.

This bug is awaiting verification that the linux-oem-5.14/5.14.0-1021.23 kernel in -proposed solves the problem. Please test the kernel and update this bug with the results. If the problem is solved, change the tag 'verification-needed-focal' to 'verification-done-focal'. If the problem still exists, change the tag 'verification-needed-focal' to 'verification-failed-focal'.

If verification is not done by 5 working days from today, this fix will be dropped from the source code, and this bug will be closed.

See https://wiki.ubuntu.com/Testing/EnableProposed for documentation how to enable and use -proposed. Thank you!
