doc reference errors (make refcheckdocs):

See https://patchwork.ozlabs.org/patch/1590838

This check can fail if there are any dependencies. The base for a patch
series is generally the most recent rc1.

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.

Hi Rob

Thank you fou your useful information, and we will update it for next
version.

Thanks
