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.
