kbuild: allow to run dt_binding_check without kernel configuration
The dt_binding_check target is located outside of the
'ifneq ($(dtstree),) ... endif' block.
So, you can run 'make dt_binding_check' on any architecture.
This makes a perfect sense because the dt-schema is arch-agnostic.
The only one problem I see is that scripts/dtc/dtc is not always built.
For example, ARCH=x86 defconfig does not define CONFIG_DTC. Kbuild
descends into scripts/dtc/ with doing nothing. Then, it fails to build
*.example.dt.yaml files.
Let's build scripts/dtc/dtc forcibly when running dt_binding_check.
The dt-schema does not depend on any CONFIG option either, so you
should be able to run dt_binding_check without the .config file.
Going forward, you can directly run 'make dt_binding_check' in a
pristine source tree.
