cy82c693: add ->set_dma_mode method
* Fix SWDMA/MWDMA masks in cy82c693_chipset. * Add IDE_HFLAG_CY82C693 host flag and use it in ide_tune_dma() to check whether the DMA should be enabled even if ide_max_dma_mode() fails. * Convert cy82c693_dma_enable() to become cy82c693_set_dma_mode() and remove no longer needed cy82c693_ide_dma_on(). Then set IDE_HFLAG_CY82C693 instead of IDE_HFLAG_TRUST_BIOS_FOR_DMA in cy82c693_chipset. * Bump driver version. As a result of this patch cy82c693 driver will configure and use DMA on all SWDMA0-2 and MWDMA0-2 capable ATA devices instead of relying on BIOS.
