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
