For target/riscv, the CPU type name is always the combination of the
CPU model name and suffix. The CPU model names have been correctly
shown in riscv_cpu_list_entry() and riscv_cpu_add_definition()

Use generic helper cpu_mdoel_from_type() to show the CPU model names
in the above two functions, and adjusted format of the output from
riscv_cpu_list_entry() to match with other targets. Besides, the
function riscv_cpu_class_by_name() is improved by renaming @cpuname
to @model since it's for the CPU model name, and merging the condtion
of "@oc == NULL" to object_class_dynamic_cast().

Tested with "-cpu help" and "query-cpu-definitions". LGTM
