libata: relocate forcing PIO0 on reset
Forcing PIO0 on reset was done inside ata_bus_softreset(), which is a
bit out of place as it should be applied to all resets - hard, soft
and implementation which don't use ata_bus_softreset(). Relocate it
such that...
* For new EH, it's done in ata_eh_reset() before calling prereset.
* For old EH, it's done before calling ap->ops->phy_reset() in
ata_bus_probe().
This makes PIO0 forced after all resets. Another difference is that
reset itself is done after PIO0 is forced.
