ide: add ->dma_check method
* Add (an optional) ->dma_check method for checking if DMA can be
used for a given command and fail DMA setup in ide_dma_prepare()
if necessary.
* Convert alim15x3 and trm290 host drivers to use ->dma_check.
* Rename ali15x3_dma_setup() to ali_dma_check() while at it.
There should be no functional changes caused by this patch.
