|    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.

replaces pcibios_scan_root with pci_scan_bus_parented...

but in pcibios_scan_root we have a DMI check:

    dmi_check_system(pciprobe_dmi_table);

when when have several peer root buses this could be called multiple
times (which is bad), so move that call to pci_access_init().
