kbuild: allow to run dt_binding_check and dtbs_check in a single command

Browse source 
Since commit 93512dad33 ("dt-bindings: Improve validation build error
handling"), 'make dtbs_check' does not validate the schema fully.

If you want to check everything, you need to run two commands separately.

  $ make ARCH=arm dt_binding_check
  $ make ARCH=arm dtbs_check

They are exclusive each other, so you cannot do like this:

  $ make ARCH=arm dt_binding_check dtbs_check

In this case, dt-doc-validate and dt-extract-example are skipped
because CHECK_DTBS is set.

Let's make it possible to run these two targets in a single command.
It will be useful for schema writers.

@ -147,6 +147,10 @@ Note that ``dtbs_check`` will skip any binding schema files with errors. It is
necessary to use ``dt_binding_check`` to get all the validation errors in the
binding schema files.
It is possible to run both in a single command::
make dt_binding_check dtbs_check
It is also possible to run checks with a single schema file by setting the
``DT_SCHEMA_FILES`` variable to a specific schema file.
