The "+" character was not meant to be included in this set, so we had to add a hack there to still allow the legacy names of POWER and Sparc64 CPUs. However, instead of putting such a hack in the common QOM code, there is a much better place to do this: The sparc_cpu_class_by_name() function which is used to look up the names of all Sparc CPUs. Thus let's finally get rid of the "+" in the Sparc CPU names, and provide backward compatibility for the old names via some simple checks in the sparc_cpu_class_by_name() function.
