cs5530/sc1200: DMA support cleanup
sc1200.c:
* remove open-coded variant of ide_dma_host_off() (== ->dma_host_off),
it is not needed because ->dma_off_quietly calls ->dma_host_off
* use ->dma_host_on (== ide_dma_host_on() for this driver) instead of
open-coded variant, call it from the users of sc1200_config_dma2()
[ there is no need to call ->dma_host_on in sc1200_config_dma() because
core code takes care of calling ->ide_dma_on on successful execution
of ->ide_dma_check ]
* add comment about ->tuneproc interface abuse
cs5530.c/sc1200.c:
* core code takes care of calling ->dma_off_quietly before calling
->ide_dma_check so there is no need to call it in ->ide_dma_check methods
* bump driver version
