x86/pci: removing subsys_initcall ordering dependencies
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.
