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.
