ide-pmac: PIO mode setup fixes (take 3)
* Add { 0, 0 } entry to {kauai,shasta}_pio_timings[] so kauai_lookup_timing()
always returns a valid PIO timing (fixes PIO timing not being set for devices
with minimum PIO cycle <= 120ns).
* Add setting transfer mode on the device to pmac_ide_set_pio_mode().
* Fix pmac_ide_set_pio() to always program chipset for given PIO timing instead
of only when the device we want to program PIO timing for is the currently
selected one.
* Now that pmac_ide_set_pio() is fixed there is no need to set transfer mode
on the device and program chipset for PIO in pmac_ide_tune_chipset()
(returning 0 == success is not entirely correct but is OK for now since
the upper layers are only checking ->speedproc return value for DMA modes).
v2:
* s/speed/XFER_PIO_0 + pio/ in pmac_ide_set_pio_mode() so it actually compiles.
* Removal of kauai_lookup_timing() return value checking went to separate patch.
v3:
* Use XFER_PIO_0 not XFER_PIO. (Noticed by Ben)
