cs5530/sc1200: add ->udma_filter methods

CS5530/SC1200 specifies that two drives on the same cable cannot mix
UDMA/MDMA.  Add {cs5530,sc1200}_udma_filter() to handle this.  This also
makes it possible to remove open-coded best DMA mode selection and use
standard ide_use_dma()/ide_max_dma_mode() helpers.  While at it bump
version numbers.

There should be no functionality changes caused by this patch.
