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
