Masahiro pointed out the use of if_changed_rule is incorrect and command line changes are not correctly accounted for. To fix this, split up the DT binding validation target, dt_binding_check, into multiple rules for each step: yamllint, schema validtion with meta-schema, and building the processed schema. One change in behavior is the yamllint or schema validation will be re-run again when there are warnings present.
