the field contains upper-cased cpu model name and is used
for printing supported cpu model names for '-cpu help'.

Considering that cpu model lookup in superh_cpu_class_by_name()
is case-insensitive, we can drop upper-casing when
printing supported cpus list and use cpu type directly
to do the same by cutting out SUPERH_CPU_TYPE_SUFFIX from
typename.

It allows to remove SuperHCPUClass::name, which practically
duplicates names defined by TYPE_SH*_CPU definitions and
simplify sh*_class_init()/SuperHCPUClass a bit.
