While it is possible to validate all generated dtb files against the schema, it typically results in huge pile of warnings. While working on a platform it is quite useful to validate just a single file against schema. Allow specifying CHECK_DTBS=1 on a make command line to enable validation while building dtb files. This reuses the infrastructure existing for `make dtbs_check`, making dtbs_check a shortcut for `make CHECK_DTBS=1 dt_binding_check dtbs`.
