cs5530/sc1200: add PIO autotune fallback to ->ide_dma_check 

* Add PIO autotune fallback to ->ide_dma_check.

  Since cs5530/sc1200 allow separate PIO and DMA timings, and cs5530/sc1200
  always set ->autotune this change shouldn't have any other effect than
  bringing these drivers in-line with other host drivers wrt ->ide_dma_check
  implementations.

* Fix ->ide_dma_check to return "-1" if DMA cannot be set.

* Bump driver version.
