    ide: switch to DMA-mapping API
    
    * pci_map_sg() -> dma_map_sg() in ide_build_sglist().
    
    * pci_unmap_sg() -> dma_unmap_sg() in ide_destroy_dmatable().
    
    There should be no functionality changes caused by this patch except
    for blackfin arch whose dma_[un]map_sg() implementation differs from
    pci_[un]map_sg() one (on s390 arch there is no PCI, on avr32 and h8300
    archs PCI is currently unsupported, on m32r arch PCI support depends
    on BROKEN, on m68k arch PCI support depends on HADES which in turn
    depends on BROKEN, on all other archs dma_[un]map_sg() functionality
    matches with pci_[un]map_sg() one).
    
    blackfin behavior change was ack-ed by Bryan Wu.
