ice: Use ice_adapter for PTP shared data instead of auxdev

Use struct ice_adapter to hold shared PTP data and control PTP
related actions instead of auxbus. 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.
