[PATCH v4 06/18] dt-bindings: usb: Add Qualcomm PMIC Type-C controller YAML schema

Add a YAML binding for the Type-C silicon interface inside Qualcomm's
pm8150b hardware block.

The Type-C driver operates with a pdphy driver inside of a high level
single TCPM device.

Based on original work by Wesley.
