* 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.

* Return 0 instead of dev->irq in ->init_chipset implementations.
* Fix ->init_chipset method to return 'int' value instead of
'unsigned int' one.
This fixes ->init_chipset handling for host drivers (cs5530, hpt366
and pdc202xx_new) for which it is possible for this method to fail.

Move apparently misplaced read_sff_dma_status() method from 'struct ide_tp_ops'
to 'struct ide_dma_ops', renaming it to dma_sff_read_status() and making only
required for SFF-8038i compatible IDE controller drivers (greatly cutting down
the number of initializers) as its only user (outside ide-dma-sff.c and such
drivers) appears to be ide_pci_check_simplex() which is only called for such
controllers...

* Set IDE_HFLAG_SERIALIZE explictly for CMD646.
* Remove no longer needed ide_cmd646 chipset type (which has
a nice side-effect of fixing handling of unexpected IRQs).
