Bug Description
[Impact]
Error message "ucsi_acpi USBC000:00: GET_CONEECTOR_
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.
