phy: qcom-qmp-combo: Introduce orientation variable

In multiple places throughout the driver code has been written in
prepration for handling of orientation switching.

Introduce a typec_orientation in qmp_combo and fill out the various
"placeholders" with the associated logic. By initializing the
orientation to "normal" this change has no functional impact, but
reduces the size of the upcoming introduction of dynamic orientation
switching.
