We are going to add more init for the latest machine, so move the setup
to a function so we don't have to change the DEFINE_SPAPR_MACHINE macro
each time.

Not sure about the meaning of "change the DEFINE_SPAPR_MACHINE macro" but
yes, if we don't put the additional init there, we would be forced to
move it around each time to the new default machine init.

But we can have only 1 default per QEMU binary... How PPC manage having
multiple defaults? The first or last listed is choosen as default?

IIUC it isn't about putting multiple defaults here. It is about putting
any additional init for the default machine type that we cannot put in
spapr_machine_class_init(), instead of putting it in the versioned
init function, eg. spapr_machine_5_0_class_options(). Otherwise this
would force us to carry the change when we add a new machine version.

Maybe it's cleaner to pass the latest flag to
spapr_machine_latest_class_options? Rename it spapr_machine_default_class_options?
This way we don't need to bother clearing is_default in other
machine types, we'll only set it for the latest one.
