Wojciech Macek 52ea10af69 Improve ThunderX PEM driver to work on pass2 revision
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.
