Subject: [PATCH] [PATCH] libata: use SATA speed down in
 ata_drive_probe_reset()

Make ata_drive_probe_reset() use SATA SPD configuration.  Hardreset
will be force if speed renegotiation is necessary.  Also, if a
hardreset fails, PHY speed is stepped down and hardreset is retried
until the lowest speed is reached.
