(de)activate for pcmcia cards.
Implement detach/(de)activate for PCI cards.
Clean up internal state (free call-descriptors) if a controller is

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.
the generic layer 4 and layer 3 management system.
This should make the layer 4 driver API LKM clean - finaly.
Make the Fritz!PCI driver work again after resent changes (oops!),
noted by Frank Kardel (PR 15948) and Matthias Scheeler.
