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.
