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.
