sc1200: fix ->dma_base equal zero handling
Set hwif->atapi_dma/{ultra,mwdma}_mask and drive->autodma after checking that
->dma_base exists. If ->dma_base is not set (== PCI BAR4 cannot be reserved)
then DMA hooks shouldn't be initialized or bad things will happen.
OTOH hwif->set_{pio,dma}_mode hooks should be set even if hwif->dma_base == 0.
