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.
