Subject: [PATCH 12/21] PCI: Merge pci_dev_resource_x and pci_dev_resource
pci_dev_resource_x is superset of pci_dev_resource
and those two are temp struct during resource reallocating.
pci_dev_resource usage is quite limted.
So just use pci_dev_resource_x, and rename it as new pci_dev_resource.
-v2: According to Linus, Separate free_list change to another patch
