[PATCH v3 4/7] dt-bindings: usb: Add Qualcomm PMIC PDPHY controller YAML schema

[Bryan O'Donoghue <bryan.odonoghue@linaro.org>]

Add a YAML binding for the power-delivery PHY silicon interface inside
Qualcomm's pm8150b hardware block.

The pdphy driver operates with a type-c driver inside of a high level
single TCPM device to provide overall TCPM functionality.
