Notes:
    v1->v2:
    Change the two Document from txt to yaml.
    
    v2->v3:
    Fix formatting errors.
    
    v3->v4:
    Fix bugs in the two yaml files.
    
    v4->v5:
    No change.
    
    v5->v6:
    Rewrite the two yaml files.
    
    v6->v7:
    1.Update compatible strings in "ingenic,cpu.yaml".
    2.Fix formatting errors, and enum for compatible strings.
    3.Remove unnecessary "ingenic,soc.yaml".
    
    v7->v8:
    No change.
