3.16.72-rc1 review patch. If anyone has any objections, please let me know.

------------------

From: Andre Przywara <andre.przywara@xxxxxxx>

commit 9cde402a59770a0669d895399c13407f63d7d209 upstream.

There is a Marvell 88SE9170 PCIe SATA controller I found on a board here.
Some quick testing with the ARM SMMU enabled reveals that it suffers from
the same requester ID mixup problems as the other Marvell chips listed
already.

Add the PCI vendor/device ID to the list of chips which need the
workaround.
