This patch adds in some NCQ blacklist entries taken from the Silicon
Image Windows drivers' .inf files for the 3124 and 3132 controllers.
These entries were marked as ""DisableSataQueueing". Assume these are
in their blacklist for a reason and disable NCQ on these drives.

The general consensus of private emails seems to be that its ok to blacklist the Maxtor one, at least.

So let's go ahead and at least get that entry in.
