libata: implement LPM support for port multipliers Port multipliers can do DIPM on fan-out links fine. Implement support for it. Tested w/ SIMG 57xx and marvell PMPs. Both the host and fan-out links enter power save modes nicely. SIMG 37xx and 47xx report link offline on SStatus causing EH to detach the devices. Blacklisted.
