sas_discover_sata() notifies lldds of sata devices twice. Once to allow the 'identify' to be sent, and a second time to allow aic94xx (the only libsas driver that cares about sata_dev.identify) to setup NCQ parameters before the device becomes known to the midlayer. Replace this double notification and intervening 'identify' with an explicit ->lldd_ata_set_dmamode notification. With this change all ata internal commands are issued by libata, so we no longer need sas_issue_ata_cmd(). The data from the identify command only needs to be cached in one location so ata_device.id replaces domain_device.sata_dev.identify.
