ide: add ->dma_timer_expiry method and remove ->dma_exec_cmd one (v2)
* Rename dma_timer_expiry() to ide_dma_sff_timer_expiry() and export it.
* Add ->dma_timer_expiry method and use it to set hwif->expiry for
ATA_PROT_DMA protocol in do_rw_taskfile().
* Initialize ->dma_timer_expiry to ide_dma_sff_timer_expiry() for SFF hosts.
* Move setting hwif->expiry from ide_execute_command() to its users and drop
'expiry' argument.
* Use ide_execute_command() instead of ->dma_exec_cmd in do_rw_taskfile().
* Remove ->dma_exec_cmd method and its implementations.
* Unexport ide_execute_command() and ide_dma_intr().
v2:
* Fix CONFIG_BLK_DEV_IDEDMA=n build (noticed by Randy Dunlap).
* Fix *dma_expiry naming (suggested by Sergei Shtylyov).
There should be no functional changes caused by this patch.
