Things changed:
* do not allocate 4GB of SLI space, because it's the waste of
system resources. Allocate only small portions when needed.
* provide own implementation of activate_resource which performs
address translation between PCI bus and host PA address space.
This is temporary solution, should be replaced by bus_map_resource
once implemented.
