ide: use only ->set_pio_mode method for programming PIO modes (take 2)
Use ->set_pio_mode method to program PIO modes in ide_set_xfer_rate()
(the only place which used ->speedproc to program PIO modes) and remove
handling of PIO modes from all ->speedproc implementations.
v2:
* Fix pmac_ide_tune_chipset() comment.
There should be no functionality changes caused by this patch.
