Jonas Gorski e7b5dd0e1d image.mk: add a BuildDTB define
Add a Image/BuildDTB command that takes the path to an dts file and
applies the CPP using the default include directories, then uses dtc
to compile the dts as the specified output file.
Additional CPP and DTC flags can be supplied as additional arguments.
