conf/machine/include: Cleanup IA tunings to match README

We perform a basic cleanup of the IA32 architecture and related
tunings in order to match the rules and descriptions within the
new tuning README file.

A number of small issues were corrected in the "c3" tuning to
bring it inline with the README.
