ide: add IDE_HFLAG_ABUSE_SET_DMA_MODE host flag
* Add IDE_HFLAG_ABUSE_SET_DMA_MODE host flag and use it to decide
what to do with transfer modes < XFER_PIO_0 in ide_set_xfer_rate().
* Set IDE_HFLAG_ABUSE_SET_DMA_MODE in host drivers that need it
(aec62xx, amd74xx, cs5520, cs5535, hpt34x, hpt366, pdc202xx_old,
serverworks, tc86c001 and via82cxxx) and cleanup ->set_dma_mode
methods in host drivers that don't (IDE core code guarantees that
->set_dma_mode will be called only for modes which are present
in SWDMA/MWDMA/UDMA masks).
While at it:
* Add IDE_HFLAGS_HPT34X/HPT3XX/PDC202XX/SVWKS define in
hpt34x/hpt366/pdc202xx_old/serverworks host driver.
There should be no functionality changes caused by this patch.
