Introduce the dt-binding for enabling USB type C orientation and role detection using the PM8150B. The driver will be responsible for receiving the interrupt at a state change on the CC lines, reading the orientation/role, and communicating this information to the remote clients, which can include a role switch node and a type C switch.
