There is no good reason to duplicate the PCI menu in every architecture. Instead provide a selectable HAS_PCI symbol that indicates availability of PCI support and the handle the rest in drivers/pci. Note that for powerpc we now select HAS_PCI globally instead of the convoluted mess of conditional or or non-conditional support per board, similar to what we do e.g. on x86. For alpha PCI is selected for the non-jensen configs as it was the default before, and a lot of code does not compile without PCI enabled. On other architectures with limited PCI support that wasn't as complicated I've left the selection as-is.
