Subject: [PATCH v2 4/4] arm/arm64: dts: samsung: Always enable extra W=1
 warnings

Samsung platforms are clean of W=1 dtc warnings, so enable the warnings
by default. This way submitters don't have to remember to run a W=1
build of the .dts files and the grumpiness of the maintainers can be
reduced.
