[PATCH v3 04/32] target/avr: Use generic helper to show CPU model names

[Gavin Shan <gshan@redhat.com>]

For target/avr, the CPU model name is resolved as same to the CPU
type name in avr_cpu_class_by_name(). Actually, the CPU model name
is the combination of the CPU model name and suffix.

Support the resolution from the combination of CPU model name and
suffix to the CPU type name in avr_cpu_class_by_name(), and use
the generic helper cpu_model_from_type() to show CPU model names
in cpu_list(), with adjusted format to match with other targets.
