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.

Tentative ACK: I wonder if a naked COMRESET is the best procedure for changing PHY speeds. We might even power down the phy, change speeds, and then power it up again. Need to reach my SATA docs, and maybe talk to some device/controller vendors.
