libqos: Limit spapr-pci to 32-bit MMIO for now
Currently the functions in pci-spapr.c (like pci-pc.c on which it's based) don't distinguish between 32-bit and 64-bit PCI MMIO. At the moment, the qemu side implementation is a bit weird and has a single MMIO window straddling 32-bit and 64-bit regions, but we're likely to change that in future. In any case, pci-pc.c - and therefore the testcases using PCI - only handle 32-bit MMIOs for now. For spapr despite whatever changes might happen with the MMIO windows, the 32-bit window is likely to remain at 2..4 GiB in PCI space. So, explicitly limit pci-spapr.c to 32-bit MMIOs for now, we can add 64-bit MMIO support back in when and if we need it.
