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.
