usb: pd: Add support of qpnp-pdphy and policy_engine drivers 



The qpnp-pdphy driver provides support for the PD PHY peripheral.
This along with the policy engine provides a protocol stack that
supports USB Power Delivery communication over a Type-C port.
This snapshot is taken as of msm-4.19 commit <1526c9c655ff>
("Merge "mmc: sdhci-msm: Add quirk to control debug feature"").

Fixed the compilation issues related to typeC framework for
the support of role swap. Also, remove unsupported and unused
extcon framework calls and API.
