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.
