    atiixp: PIO mode setup fixes · 485efc6c
    Bartlomiej Zolnierkiewicz authored
    * Split off exisiting atiixp_tuneproc() into atiixp_tune_pio()
      and then add setting device PIO mode to atiixp_tuneproc().
    * Add missing ide_get_best_pio_mode() call to atiixp_tuneproc() so
      "pio" == 255 (autotune) is handled correctly and "pio" values > 4 && < 255
      are filtered to PIO4 (previously "pio" == 5 could result in wrong timings
      being used and "pio" values > 4 && < 255 in an OOPS).
    * Handle PIO modes early in atiixp_speedproc() so save_mdma_mode[]
      doesn't get cleared.
    * In atiixp_dma_check():
      - fix max_mode argument for ide_get_best_pio_mode()
      - don't call atiixp_dma_2_pio() so PIO1 doesn't get remapped to PIO0
      - use atiixp_tuneproc() instead of atiixp_speedproc()
    * Bump driver version.
