This patch adds in some NCQ blacklist entries taken from the Silicon

These entries were marked as ""DisableSataQueueing". Assume these are
in their blacklist for a reason and disable NCQ on these drives.

Do we have information that these drives fail on non-SiI controllers?

Sometimes the problem can be related to a single family of controllers.
