Turned out to cause trouble on single IOH machines, and is superceded by
_CRS on multi-IOH machines with production BIOSes.

Those functions are used by intel_bus.c so seperate them to another file. and
make amd_bus a bit smaller.

We use dev_dbg() in arch/x86/pci, but there's no easy way to turn it
on. Add -DDEBUG when CONFIG_PCI_DEBUG=y, just like we do in drivers/pci.

For intel systems with multi IOH, we should read peer root resources
directly from PCI config space, and don't trust _CRS.

first step: make the VISWS subarch boot on a regular PC.
We take various shortcuts for that. We copy the generic arch setup file over
into the VISWS setup file.
This is the only step that is not expected to boot on a real VISWS.

So far subsys_initcalls has been executed in this order depending on
the object order in the Makefile:
arch/x86/pci/visws.c:subsys_initcall(pcibios_init);
arch/x86/pci/numa.c:subsys_initcall(pci_numa_init);
arch/x86/pci/acpi.c:subsys_initcall(pci_acpi_init);
arch/x86/pci/legacy.c:subsys_initcall(pci_legacy_init);
arch/x86/pci/irq.c:subsys_initcall(pcibios_irq_init);
arch/x86/pci/common.c:subsys_initcall(pcibios_init);
This patch removes the ordering dependency. There is now only one
subsys_initcall function that contains subsystem initialization code
with a defined order.

This should be safe since mmconfig*.o and init.o do not contain
*initcalls with the same level as in other files.
