sata_mv add basic port multiplier support
Add basic port-multiplier support to sata_mv.
This works in Command-based-switching mode for Gen-II chipsets,
and in FIS-based-switching mode for Gen-IIe chipsets.
Error handling remains at the primary port level for now
(works okay, but not great). This will get fixed in a subsequent
patch series for IRQ/EH handling fixes. There are also some
known NCQ/PMP errata to be dealt with in the near future,
once we have this basic PMP support in place.
