Subject: Add a class field to devconf and mst drivers. For those where it was
 easy, drivers were also fixed to call dev_attach() during probe rather than
 attach (in keeping with the new design articulated in a mail message five
 months ago).  For a few that were really easy, correct state tracking was
 added as well. The `fd' driver was fixed to correctly fill in the
 description. The CPU identify code was fixed to attach a `cpu' device.  The
 code was also massively reordered to fill in cpu_model with somethingremotely
 resembling what identifycpu() prints out.  A few bytes saved by using %b to
 format the features list rather than lots of ifs.
