ide: convert ide_find_best_mode() users to use ide_max_dma_mode()
ide-timing.h: * remove handling of DMA modes from ide_find_best_mode() and rename it to ide_find_best_pio_mode() * drop no longer needed "map" argument from ide_find_best_pio_mode() and delete needless ->id check * remove no longer needed XFER_SWDMA and XFER_UDMA* defines au1xxx-ide.c: * use ide_max_dma_mode() instead of ide_find_best_mode() * remove needless CONFIG_BLK_DEV_IDE_AU1XXX_MDMA2_DBDMA #ifdef amd74xx.c: * store UDMA masks in amd_ide_chip[] and while at it make "base" field to be u8 instead of unsigned long * convert the driver to use UDMA masks from amd_ide_chip[] * use ide_max_dma_mode() and ide_find_best_pio_mode() instead of ide_find_best_mode() * delete stale comment from amd74xx_ide_dma_check() * remove no longer needed AMD_UDMA* defines via82cxxx.c: * remove unused DISPLAY_VIA_TIMINGS define * store UDMA masks in via_isa_bridges[] and while at it make "flags" field to be u8 instead of u16 * convert the driver to use UDMA masks from via_isa_bridges[] * use ide_max_dma_mode() and ide_find_best_pio_mode() instead of ide_find_best_mode() * remove no longer needed VIA_UDMA* defines pmac.c: * use ide_max_dma_mode() instead of ide_find_best_mode() There should be no functionality changes caused by this patch.
