Series arm64: qcom: sm8550: retrieve USB-C port orientation from gpio | expand

Commit Message

Neil Armstrong Aug. 4, 2023, 1:50 p.m. UTC 
On SM8450 and SM8550 based platforms, the Type-C plug orientation is given on a
GPIO line set by the PMIC.

Document this optional Type-C connector property, and take the
assumption an active level represents an inverted/flipped orientation.
