ide: rework the code for selecting the best DMA transfer mode (v3)
Depends on the "ide: fix UDMA/MWDMA/SWDMA masks" patch. * add ide_hwif_t.udma_filter hook for filtering UDMA mask (use it in alim15x3, hpt366, siimage and serverworks drivers) * add ide_max_dma_mode() for finding best DMA mode for the device (loosely based on some older libata-core.c code) * convert ide_dma_speed() users to use ide_max_dma_mode() * make ide_rate_filter() take "ide_drive_t *drive" as an argument instead of "u8 mode" and teach it to how to use UDMA mask to do filtering * use ide_rate_filter() in hpt366 driver * remove no longer needed ide_dma_speed() and *_ratemask() * unexport eighty_ninty_three() v2: * rename ->filter_udma_mask to ->udma_filter [ Suggested by Sergei Shtylyov <sshtylyov@ru.mvista.com>. ] v3: * updated for scc_pata driver (fixes XFER_UDMA_6 filtering for user-space originated transfer mode change requests when 100MHz clock is used) Signed-off-by: Bartlomiej Zolnierkiewicz <bzolnier@gmail.com>
