Revert "libata: check SATA_SETTINGS log with HW Feature Ctrl"
This reverts commit de90cd71f68e947d3bd6c3f2ef5731ead010a768. Shane Huang writes: Please suspend this patch because I just received two new DevSlp drives but found word 78 bit 5 is _not_ set. I'm checking with the drive vendor whether he gave me the wrong information. If bit 5 is not the necessary and sufficient condition, I will implement another patch to replace ata_device->sata_settings into ->devslp_timing. Signed-off-by: Jeff Garzik <jgarzik@redhat.com>
