martin 0bc69b6498 Now that we have all the pieces of the puzzle available start to unriddle 
and move them in their proper places.

Move the BRI registry from layer 2 (duh!) to layer 4, so active cards
(which don't have layer 3 or layer 2 in their driver). Remove all remaining
hard coded controller and driver types. Remove any arbitrary hard coded
limits, at least those that show up in the internal API.

This fixes PR 15950.
