Subject[PATCH 1/2] dt-bindings: connector: Add child nodes for multiple PD capabilities
From
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. caps0, caps1) which is a child
node under "capabilities". Each node contains PDO data of a selectable
Power Delivery capability.
