For target/loongarch, the CPU type name can be: (1) the combination of
the CPU model name and suffix; (2) same to the CPU model name. The CPU
model names have been shown correctly in loongarch_cpu_list_entry()
and loongarch_cpu_add_definition() by following (1).

Use generic helper cpu_model_from_type() in above two functions to
show the CPU model names. The format of the output from cpu_list()
is also adjusted to match with other targets.
