I gave it a try. Patch below.
But that is still not sufficient:

| arch/powerpc/platforms/built-in.o:(.toc1+0x4e8): undefined reference to `pci_io_base'

due to arch/powerpc/platforms/cell/io-workarounds.c. I guess this file
shouldn't be built when CONFIG_PCI=n?

As I don't have the hardware to test anyway, I'll give up.
