[PATCH] libata: add NCQ blacklist entries from Silicon Image Windows driver (v2) 

This adds some NCQ blacklist entries taken from the Silicon Image 3124/3132
Windows driver .inf files. There are some confirming reports of problems
with these drives under Linux (for example http://lkml.org/lkml/2007/3/4/178

)
so let's disable NCQ on these drives.

 [ I'm personally starting to wonder whether we shouldn't disable NCQ by
   default, and perhaps have a white-list. There seems to be a *lot* of
   drives that do this wrong..   - Linus ]
