x86-64: introduce struct pci_sysdata to facilitate sharing of ->sysdata
This patch introduces struct pci_sysdata to x86 and x86-64, and
converts the existing two users (NUMA, Calgary) to use it.
This lays the groundwork for having other users of sysdata, such as
the PCI domains work.
The Calgary bits are tested, the NUMA bits just look ok.

that replace pcibios_scan_root by pci_scan_bus_parented...
- bus = pcibios_scan_root(busnum);
+ sd->node = -1;
+
+ pxm = acpi_get_pxm(device->handle);
+#ifdef CONFIG_ACPI_NUMA
+ if (pxm >= 0)
+ sd->node = pxm_to_node(pxm);
+#endif
+
+ bus = pci_scan_bus_parented(NULL, busnum, &pci_root_ops, sd);
and in pcibios_scan_root we have
struct pci_bus *bus = NULL;
struct pci_sysdata *sd;
dmi_check_system(pciprobe_dmi_table);
while ((bus = pci_find_next_bus(bus)) != NULL) {
if (bus->number == busnum) {
/* Already scanned */
return bus;
}
}
