be the beginning of our move to a more dynamic (configuration manager) based setup for all drivers. Everything seems to work except for some devconf problems. Only the aic7xxx driver will be using this interface until it is reviewed, revised and accepted as a good configuration interface. Adapt aic7770.c to use new eisaconf. eisadevs.c is replaced by a linker set.
