If CONFIG_PCI=n and gcc (e.g. 4.1.2) decides not to inline
get_pci_function_alias_group(), the build fails with:
drivers/iommu/iommu.o: In function `get_pci_function_alias_group':
iommu.c:(.text+0xfdc): undefined reference to `pci_acs_enabled'
Due to the various dummies for PCI calls in the CONFIG_PCI=n case,
pci_acs_enabled() never called, but not all versions of gcc are smart
enough to realize that.
While explicitly marking get_pci_function_alias_group() inline would fix
the build, this would inflate the code for the CONFIG_PCI=y case, as
get_pci_function_alias_group() is a not-so-small function called from two
places.
Hence fix the issue by introducing a dummy for pci_acs_enabled() instead.
