powerpc: Add sync_*_for_* to dma_ops
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.
