>    dma-direct: merge swiotlb_dma_ops into the dma_direct code
>    
>    While the dma-direct code is (relatively) clean and simple we actually
>    have to use the swiotlb ops for the mapping on many architectures due
>    to devices with addressing limits.  Instead of keeping two
>    implementations around this commit allows the dma-direct
>    implementation to call the swiotlb bounce buffering functions and
>    thus share the guts of the mapping implementation.  This also
>    simplified the dma-mapping setup on a few architectures where we
>    don't have to differenciate which implementation to use.
