ide: add struct ide_dma_ops (take 3)
Add struct ide_dma_ops and convert core code + drivers to use it.
While at it:
* Drop "ide_" prefix from ->ide_dma_end and ->ide_dma_test_irq methods.
* Drop "ide_" "infixes" from DMA methods.
* au1xxx-ide.c:
- use auide_dma_{test_irq,end}() directly in auide_dma_timeout()
* pdc202xx_old.c:
- drop "old_" "infixes" from DMA methods
* siimage.c:
- add siimage_dma_test_irq() helper
- print SATA warning in siimage_init_one()
* Remove no longer needed ->init_hwif implementations.
v2:
* Changes based on review from Sergei:
- s/siimage_ide_dma_test_irq/siimage_dma_test_irq/
- s/drive->hwif/hwif/ in idefloppy_pc_intr().
- fix patch description w.r.t. au1xxx-ide changes
- fix au1xxx-ide build
- fix naming for cmd64*_dma_ops
- drop "ide_" and "old_" infixes
- s/hpt3xxx_dma_ops/hpt37x_dma_ops/
- s/hpt370x_dma_ops/hpt370_dma_ops/
- use correct DMA ops for HPT302/N, HPT371/N and HPT374
- s/it821x_smart_dma_ops/it821x_pass_through_dma_ops/
v3:
* Two bugs slipped in v2 (noticed by Sergei):
- use correct DMA ops for HPT374 (for real this time)
- handle HPT370/HPT370A properly
