cpu/intel/model_206ax: Always return a package from _CST
The _CST method is supposed to return a package. If a mainboard used zero for all ACPI C-states, the generated _CST would return nothing, which is invalid. Instead, return a package with no C-state entries. This change is a no-op, since all mainboards have at least one valid ACPI C-state. This is what `acpigen_write_CST_package()` does, too.
