libata: add @spd_limit to sata_down_spd_limit()
Add @spd_limit to sata_down_spd_limit() so that the caller can specify the SPD limit it wants. This parameter doesn't get in the way even when it's too low. The closest possible limit is applied. Signed-off-by: Tejun Heo <tj@kernel.org> Signed-off-by: Jeff Garzik <jgarzik@redhat.com>
