ACPI requires to run acpi_pci_{add|remove}_bus while new PCI bus is created.
This allows to do some ACPI-specific additional configuration, like
PCI hotplug slot enumeration. In order to fulfill these requirements,
we implement arch-specific pcibios_{add|remove}_bus calls
and call acpi_pci_{add|remove}_bus from there.
