This adds the build infrastructure for checking DT binding schema documents and validating dts files using the binding schema. Check DT binding schema documents: make dt_binding_check Build dts files and check using DT binding schema: make dtbs_check Optionally, DT_SCHEMA_FILES can be passed in with a schema file(s) to use for validation. This makes it easier to find and fix errors generated by a specific schema. Currently, the validation targets are separate from a normal build to avoid a hard dependency on the external DT schema project and because there are lots of warnings generated.
