piix/slc90e66: fix PIO1 handling in ->speedproc method (take 2) 

* Don't call {piix,slc90e66}_dma_2_pio() for PIO modes in
  {piix,slc90e66}_tune_chipset().

* Add PIO1 handling to {piix,slc90e66}_tune_chipset().

* Bump driver version.  

v2:
* Remove PIO modes from {piix,slc90e66}_dma_2_pio(), they are no longer needed
