v2->v3:
1. change dt-bindings documents from txt to yaml format.
2. Add SHUB clock to access the devices of m7

See https://patchwork.ozlabs.org/patch/1399891
The base for the patch is generally the last rc1. Any dependencies
should be noted.
If you already ran 'make dt_binding_check' and didn't see the above
error(s), then make sure 'yamllint' is installed and dt-schema is up to
date:
pip3 install dtschema --upgrade
Please check and re-submit.
