    [SCSI] don't build scsi_dma_{map,unmap} for !HAS_DMA · 7689e82e

    scsi fails to build on !HAS_DMA architectures:
    
    drivers/built-in.o(.text+0x20af6): In function `scsi_dma_map':
    : undefined reference to `dma_map_sg'
    drivers/built-in.o(.text+0x20b5c): In function `scsi_dma_unmap':
    : undefined reference to `dma_unmap_sg'
    
    I split those functions out into a new file. Builds on s390 and i386.
    
    Move scsi_dma_{map,unmap} into scsi_lib_dma.c which is only build if
    HAS_DMA is set.
