Rather than machine instances having backward-compatible option
defaults that need to be repeatedly re-enabled for every new machine
type we introduce, we set the defaults appropriate for newer machine
types, then add code to explicitly disable instance options as needed
to maintain compatibility with older machine types.
Currently pseries-2.5 does not inherit from pseries-2.6 in this
fashion, which is okay at the moment since we do not have any
instance compatibility options for pseries-2.6+ currently.
We will make use of this in future patches though, so fix it here.
