We need to swap these out once we start using swiotlb, so add them to dma_ops. Create CONFIG_PPC_NEED_DMA_SYNC_OPS Kconfig option; this is currently enabled automatically if we're CONFIG_NOT_COHERENT_CACHE. In the future, this will also be enabled for builds that need swiotlb. If PPC_NEED_DMA_SYNC_OPS is not defined, the dma_sync_*_for_* ops compile to nothing. Otherwise, they access the dma_ops pointers for the sync ops. This patch also changes dma_sync_single_range_* to actually sync the range - previously it was using a generous dma_sync_single. dma_sync_single_* is now implemented as a dma_sync_single_range with an offset of 0.
