This allows significant code simplification and faster access to the container fields used in the PTP support code. Move the PTP port list to the ice_adapter container to simplify the code and avoid race conditions which could occur due to the synchronous nature of the initialization/access and certain memory saving can be achieved by moving PTP data into the ice_adapter itself.
