Fix several issues discovered while debugging UCSI implementation on
Qualcomm platforms (ucsi_glink). With these patches I was able to
get a working Type-C port managament implementation. Tested on SC8280XP
(Lenovo X13s laptop), SM8350-HDK. Lightly tested on SC8180X Primus devices.

Depends: [1], [2], [3]
