target/ppc/cpu-models: Rename power5+ and power7+ for new QOM naming rules

The character "+" is now forbidden in QOM device names (see commit
b447378e1217 - "Limit type names to alphanumerical and some few special
characters"). For the "power5+" and "power7+" CPU names, there is
currently a hack in type_name_is_valid() to still allow them for
compatibility reasons. However, there is a much nicer solution for this:
Simply use aliases! This way we can still support the old names without
the need for the ugly hack in type_name_is_valid().
