This patchset fixes two issues on ADL-P related to the TypeC PHY
connect/disconnect sequences in patch 11 and 13 and a few other minor
TypeC issues I noticed on the way. The fix in patch 11 requires some
refactoring and it affects all TypeC platforms; this was the way that
made sense to me to keep things consistent across all platforms and
TypeC modes and also bring the connect/disconnect sequences closer to
the specification.
Tested on ICL, TGL, ADL-P, on all the 3 TypeC port types where
available.
