Commit 662a60102c12 ("usb: typec: Separate USB Power Delivery from USB Type-C") allows userspace to configure the PD of a port by selecting different set of predefined PD capabilities. Define the PD capability sets in DT for better configurability in device modules. 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.
