Other similar libraries relied on the bus-specifics being handled in inlined functions, to be compiled on demand by drivers, once the proper PCI dependency has been settled. This seems unsafe. Move the PCI-specific helpers out of the lib directory to the drivers/crypto directory, properly following the dependency hierarchy.
