In order to allow enabling extra dtc warnings on a per arch or platform basis, define a new variable, KBUILD_EXTRA_WARN_DTC, which contains the warning level and can be set by an arch or platform independently of KBUILD_EXTRA_WARN. The default value is KBUILD_EXTRA_WARN as before. The platform setting and command line setting are merged. For example, with a platform that defaults to W=1, one can run 'make W=2 dtbs' which will enable both level 1 and 2 warnings.
