kernel-devicetree: Introduce KERNEL_DTC_FLAGS to pass dtc flags
Currently DTC_FLAGS kernel makefile parameter can be specified directly on the command line by adding it to KERNEL_EXTRA_ARGS. However, this prevents scripts/Makefile.lib logic from appending flags that silence dtc warnings (all assignments done from within a makefile, to a variable specified on the command line, are ignored). Because of this, the do_compile log is cluttered with dtc warnings that should only be printed when compiling with W="123": ... /soc: node has a reg or ranges property, but no unit name /soc/gpu: missing or empty reg/ranges property /soc/firmware/gpio: missing or empty reg/ranges property ... To fix this, introduce the dedicated KERNEL_DTC_FLAGS variable to hold dtc flags and export DTC_FLAGS in the environment before generating the dtbs (make allows "+=" operations on variables that come from the environment, so the warnings are silenced properly).
