    PCI: check szhi when sz is 0 when 64 bit iomem bigger than 4G · 07eddf3d

    For pci mem resource that size is bigger than 4G, the sz returned by
    pc_size will be 0.
    So that resource is skipped, and register contained hi address will be
    treated as another 32bit resource. We need to use sz64 and pci_sz64 for
    64 bit resource for clear logical.  Typical usages for this: Opteron
    system with co-processor and the co-processor could take more than 4G
    RAM as pre-fetchable mem resource.
