media: v4l: async: Make V4L2 async match information a struct

Browse Source 
Make V4L2 async match information a struct, making it easier to use it
elsewhere outside the scope of struct v4l2_async_subdev.

Also remove an obsolete comment --- none of these fields are supposed to
be touched by drivers.
