The common approach is to only apply nodes and node properties to the
.dtsi files which are appropriate for _all_ platforms which include
them. Anything that is only relevant to a sub-set of boards should be
in a higher ranking .dtsi file and finally, any settings which are
board specific should be in the board's .dts file.
