powerpc: Add 86xx support for SWIOTLB

Browse source

This is the final bit of code to allow enabling swiotlb on
mpc86xx.  The platform-specific code is very small and consists
of enabling SWIOTLB in the config file, registering the
swiotlb_setup_bus_notifier initcall, and setting pci_dma_ops
to point to swiotlb_pci_dma_ops if we have more memory than
can be mapped by the inbound PCI windows.
