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)
