properties:
The realtime Power Delivery capabilities of a port may not be always the same under different hardware status such as the port usage of a multiple port system or the status of the battery pack. Define the PD capability sets in DT for better configurability in Type-C/PD port drivers. Define an optional child node "capabilities" to contain multiple USB Power Delivery capabilities. Define child nodes with pattern (e.g. caps-0, caps-1) under "capabilities". Each node contains PDO data of a selectable Power Delivery capability. Also define common properties for source-pdos, sink-pdos, and op-sink-microwatt that can be referenced.
