This adds both raid class support and SPI transport class support (the
raid classes are built on top of the SPI transport class support, so it
just seemed easier to combine the two patches). The raid class features
are quite primitive, but it can now show the state of the raid array and
the resync completion fraction. The next project will be to add a piece
state model allowing the individual raid pieces to be taken on and
offline.
