usb: typec: qcom-pmic-typec: allow different implementations for the port backend 

Follow the PD PHY changes and rework Type-C port implementation to
become an encapsulated backend. While this is not required for the
PMI632, it will us later to enable Type-C handling on earlier platforms,
including, but not limited to SDM845, SDM660 and MSM8998.
