siimage: PIO mode setup fixes (take 2)
* Add sil_tuneproc() wrapper for siimage_tuneproc() which also sets
PIO mode on the device.
* Add missing ide_get_best_pio_mode() call to sil_tuneproc() so
"pio" == 255 (autotune) is handled correctly (previously PIO0 was used)
and "pio" values > 4 && < 255 are filtered to PIO4 (instead of PIO0).
* Add code limiting maximum PIO mode according to the pair device capabilities
to sil_tuneproc().
* Convert users of config_siimage_chipset_for_pio() to use sil_tune_pio() and
sil_tuneproc(). This fixes PIO fallback in siimage_config_drive_for_dma() to
use max PIO mode available instead of PIO4 (config_siimage_chipset_for_pio()
used wrong arguments for ide_get_best_pio_mode() and as a results always
tried to set PIO4).
* Remove no longer needed siimage_taskfile_timing()
and config_siimage_chipset_for_pio().
* Enable ->autotune unconditionally and remove PIO tuning for UDMA/MDMA modes
from siimage_speedproc()
* Bump driver version.
v2:
* Fix issues noticed by Sergei:
- correct pair device check
- trim only taskfile PIO to the slowest of the master/slave
- enable ->autotune unconditionally and remove PIO tuning for UDMA/MDMA modes
from siimage_speedproc()
- add TODO item for IORDY bugs
- minor cleanups
