target/sparc/cpu: Rename the CPU models with a "+" in their names

Browse Source 
Commit b447378e12 ("qom/object: Limit type names to alphanumerical ...")
cut down the amount of allowed characters for QOM types to a saner set.
The "+" character was 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.
