Define a new optional property "capabilities" which is a child node
under connector to contain multiple USB Power Delivery capabilities.
Define a new property with pattern (e.g. caps-0, caps-1) which is a
child node 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.
