[LinuxPPS] 9 May 22:01 - ide: rework the code for selecting the best DMA transfer mode (v3)

[linuxpps: Bartlomiej Zolnierkiewicz <>]

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 . ]  
  
v3:  
* updated for scc_pata driver (fixes XFER_UDMA_6 filtering for user-space  
originated transfer mode change requests when 100MHz clock is used)
