PCI: check szhi when sz is 0 when 64 bit iomem bigger than 4G
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.
