siimage: fix ->set_pio_mode method to select PIO data transfer
* Remember to select PIO data transfer (with IORDY monitored) in sil_tune_pio()
(->set_pio_mode method) so the controller is always programmed correctly for
PIO transfers (this is important if DMA is not going to be used).
* Don't set DMA/UDMA timings for PIO modes in siimage_tune_chipset().
* Bump driver version.
