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.
