Fold the now equivalent code in the ide_dma_check() method into a mere call to
ide_use_dma().  Make config_for_dma() return non-zero if DMA mode has been set
and call it from the ide_dma_check() method instead of ide_dma_on().
Also, defer writing the DMA timings to the chip registers until DMA is actually
turned on (and do not enable IORDY for DMA).  Remove unnecessary code from the
init_hwif() method, improve its looks overall, and also rename the driver's
ide_dma_check() and dma_start() methods.

The patch has been actually tested at last. :-)
Note that now this driver can be joined to the ide-use-fast-pio patch.
