[PATCH v4 16/33] target/riscv: Use generic helper to show CPU model names

[Gavin Shan]

For target/riscv, the registered CPU type name is always the
combination of the CPU model name and suffix. Use cpu_model_from_type()
to show the CPU model names.

Besides, @cpuname is renamed to @model in riscv_cpu_class_by_name()
since it points to CPU model name instead of CPU type name.
