sl82c105: program DMA/PIO timings in ->dma_start/->ide_dma_end
* Program DMA timings in sl82c105_dma_start() (->dma_start method)
before starting DMA transfer.
* Add sl82c105_dma_end() (->ide_dma_end method) to switch back to
PIO timings when DMA transfer is complete.
* In sl82c105_set_pio_mode() program timings regardless of ->using_dma
setting and in sl82c105_set_dma_mode() only cache the new timings.
* Remove no longer needed sl82c105_{ide_dma_on,off_quietly}().
