Since a number of powerpc chips are SoCs we end up having dma-able devices that are registered as platform or of_platform devices. We need to hook the archdata to setup proper dma_ops for these devices. Rather than having to add a bus_notify to each platform we add a default one at the highest priority (called first) to set the default dma_ops for of_platform and platform devices to dma_direct_ops. This allows platform code to override the ops by providing their own notifier call back. In the future to enable >4G DMA support on ppc32 we can hook swiotlb ops.
