SATA hardware features table

I just added another wiki page, a matrix of chips and associated SATA hardware features. The goal is not to exhaustively compare chips, but rather to give users information about whether or not their hardware (or to-be-purchased hardware) supports certain key features they need.

Driver developers, please review...

As always with the wiki, suggestions and additions welcome. Please only add new columns if the features are useful and asked-for -- I don't want this page to turn into a hardware vendor penis size war.
