For v2 hw, STP link from target is rejected after host reset because of a SoC bug. The STP reject will be terminated after we have sent IO from each PHY of a port. This is not an problem before, as we don't need to setup STP link from target immediately after host reset. But now, it is. Because we want to send soft-reset immediately after host reset. In order to terminate STP reject quickly, this patch send ATA reset command through each PHY of a port. Notes: ATA reset command don't need target's response. Besides, we do abort dev for each device before terminating STP reject. This is a quirk of v2 hw.
