ide: add ide_set{_max}_pio() (take 4)
* Add IDE_HFLAG_ABUSE_{PREFETCH,FAST_DEVSEL,DMA_MODES} flags
and set them in ht6560, cmd640, cmd64x and sc1200 host drivers.
* Add set_pio_mode_abuse() for checking if host driver has a non-standard
->tuneproc() implementation and use it in do_special().
* Add ide_set_pio() for setting PIO mode (it uses hwif->pio_mask to find
the maximum PIO mode supported by the host), also add ide_set_max_pio()
wrapper for ide_set_pio() to use for auto-tuning. Convert users of
->tuneproc to use ide_set{_max}_pio() where possible. This leaves only
do_special(), set_using_pio(), ide_hwif_restore() and ide_set_pio() as
a direct users of ->tuneproc.
* Remove no longer needed ide_get_best_pio_mode() calls and printk-s
reporting PIO mode selected from ->tuneproc implementations.
* Rename ->tuneproc hook to ->set_pio_mode and make 'pio' argument const.
* Remove stale comment from ide_config_drive_speed().
v2:
* Fix "ata_" prefix (Noticed by Jeff).
v3:
* Minor cleanups/fixups per Sergei's suggestions.
v4:
* Fix compile problem in drivers/ide/pci/cmd640.c
(Noticed by Andrew Morton).
* Improve some ->set_pio_mode comments.
