Log Message:
snapshot of work in progress on physical devices support:
- support pci at hypervisor. Attach one PCI bus for each bus returned by
  PHYSDEVOP_PCI_PROBE_ROOT_BUSES (it looks like xen hides ppb bridges from
  the guest OS).
- implement pci_conf_read()/pci_conf_write() using the appropriate
  PHYSDEVOP_PCI_* calls.
- call PHYSDEVOP_PCI_INITIALISE_DEVICE from pci_intr_map() to make xen
  do interrupts routing if needed, and map the hardware interrupt to
  a xen interrupt.
- add pci and associated devices to files.xen

This is enouth to have IDE controllers work in PIO mode.
TODO: bus_dma support (currently bus_dma won't translate pseudo-physical
      addresses to machine addresses), ISA support, test memory-mapped
      I/O registers.
