Like e65cc194 (ahci: Enable SB600 64bit
DMA on MSI K9A2 Platinum) and 3c4aa91f
(ahci: Enable SB600 64bit DMA on Asus M3A), this patch enables 64bit DMA
for the AHCI SATA controller of another board that has the SB600
southbridge.

In this case though we're enabling 64bit DMA for another MSI motherboard,
the K9AGM2 or MS-7327. It is new enough that all of the BIOS releases

When using my Seagate FreeAgent GoFlex eSATAp external disk enclosure,
interface errors are always seen until 1.5Gbps is negotiated [1]. This
occurs using any disk in the enclosure, and when the disk is connected
directly with a generic passive eSATAp cable, we see stable 3Gbps
operation as expected.

Blacklist 3Gbps mode to avoid dataloss and the ~30s delay bus reset
and renegotiation incurs.

In commit 7a879824 we added

however in a different behaviour: it returns an error if the
driver doesn't support the status operation. This is not
according to the API that says that when we don't support
the status operation, that we just should return a 0 value.
Only when the device isn't there anymore, we should return an
error.

The recent conversion of iTCO_wdt resulted in the driver no longer
getting loaded automatically, since it no longer has a
MODULE_DEVICE_TABLE() included. As the lpc_ich driver now creates a
platform device, auto-loading can easily be done by having a respective
module alias in place.
