sparc32: use per-device dma_ops
sparc32 is the last platform making dynamic decisions in
get_arch_dma_ops based on the bus passed in. Instead set the
iommu dma_ops at iommu probing and propagate them in
of_propagate_archdata, falling back to the NULL ops for the
direct mapping in the Leon or PCI case.
