MIPS: consolidate the swiotlb implementations
Octeon and Loongson share exactly the same code, move it into a common
implementation, and use that implementation directly from get_arch_dma_ops.
Also provide the expected dma-direct.h helpers directly instead of
delegating to platform dma-coherence.h headers.
