thunderbolt: Cache adapter specific capability offset into struct port
The adapter specific capability either is there or not if the port does not hold an adapter. Instead of always finding it on-demand we read the offset just once when the port is initialized. While there we update the struct port documentation to follow kernel-doc format. Signed-off-by: Mika Westerberg <mika.westerberg@linux.intel.com>
