[PATCH v4 07/33] target/avr: Use generic helper to show CPU model names

[Gavin Shan]

For target/avr, 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, the conversion from CPU model name to CPU type
name needs to be supported in avr_cpu_class_by_name().
