x86/PCI: Move set_pci_bus_resources_arch_default into arch/x86

Commit 30a18d6c3f1e774de656ebd8ff219d53e2ba4029 introduced a new
function to set the PCI bus resources.  Unfortunately, neither the
author, nor the committers seemed to know that we already have somewhere
to do that -- pcibios_fixup_bus().  This patch moves the hook (used only
by the K8 code) into x86-specific code where it should have been in the
first place.
