ISDN: Init ISA AVM CAPI drivers at module load time

Don't use a special CAPI solution to tell the drivers about 
ISA cards but use module parameters, just as other drivers do.

Internally use struct pci_dev to save that data - hopefully
one day the device tree will provide a nicer way to achieve this.
