Introduce `dma_ops` for the Coldfire M5441x platform, enabling both coherent and streaming DMA operations. This addition should fill the gap for DMA support integrates with the existing kernel DMA framework.
Arch dma code should not implement DMA OPS, but use the generic dma-direct code with the right helpes for handling coherency. This variant looks like it should be using the DMA_COHERENT_POOL allocator for dma coherent memory.
