media: v4l: async: Obtain async connection based on sub-device
Add v4l2_async_connection_unique() function for obtaining a struct
v4l2_async_connection, typically allocated by drivers together with their
own information on an external sub-device.
The relation between connections and sub-devices still remains 1:1 but
this code becomes more complex when the relation soon changes.
