This causes build errors when CONFIG_ACPI isn't enabled since both
acpi_pci_{add,remove}_bus() aren't defined in such a configuration:
arch/x86/pci/common.c: In function 'pcibios_add_bus':
arch/x86/pci/common.c:176:2: error: implicit declaration of function
'acpi_pci_add_bus'
arch/x86/pci/common.c: In function 'pcibios_remove_bus':
arch/x86/pci/common.c:181:2: error: implicit declaration of function
'acpi_pci_remove_bus'
