All custom ->dma_timeout implementations call the generic one thus it is
possible to have only an optional method for resetting DMA engine instead:
* Add ->dma_clear method and convert hpt366, pdc202xx_old and sl82c105
host drivers to use it.
* Always use ide_dma_timeout() in ide_dma_timeout_retry() and remove
->dma_timeout method.
* Make ide_dma_timeout() static.
There should be no functional changes caused by this patch.
