Currently, the only attributes supported for DMA memory are writecombine and coherent. Both of these allow speculative prefetches to occur. For certain use cases (e.g. content protection) there are requirements to disallow prefetching. Relatedly, there may be cases where buffering is not enough for high performance use cases and the full cache should be used. Add appropriate APIs for the strongly ordered and cached memory types for the needed use cases.
