ata_std_probeinit — initialize probing
void ata_std_probeinit (struct ata_port * ap);
ap is about to be probed. Initialize it. This function is
to be used as standard callback for ata_drive_probe_reset.
NOTE!!! Do not use this function as probeinit if a low level driver implements only hardreset. Just pass NULL as probeinit in that case. Using this function is probably okay but doing so makes reset sequence different from the original ->phy_reset implementation and Jeff nervous. :-P
