dt-bindings: connector: Add sink properties to comply with PD 3.1 spec
Add additional properties for ports supporting sink mode. The properties
define certain hardware and electrical properties such as sink load
step, sink load characteristics, sink compliance and charging adapter
Power Delivery Profile (PDP) for the connector. These properties need to
be defined for a Type-C port in compliance with the PD 3.1 spec.
