ide: add ide_set_dma() helper (v2)
* add ide_set_dma() helper and make ide_hwif_t.ide_dma_check return -1 when DMA needs to be disabled (== need to call ->ide_dma_off_quietly) 0 when DMA needs to be enabled (== need to call ->ide_dma_on) 1 when DMA setting shouldn't be changed * fix IDE code to use ide_set_dma() instead if using ->ide_dma_check directly v2: * updated for scc_pata Signed-off-by: Bartlomiej Zolnierkiewicz <bzolnier@gmail.com>
