Pull in recent changes from the main dtc repository. These changes primarily allow multiple device trees to be declared which are merged by dtc. This feature allows us to include a basic dts file and then provide more information for the specific system through the merging functionality. Changes pulled from git://git.jdl.com/software/dtc.git commit id: 37c0b6a0, "dtc: Add code to make diffing trees easier" Signed-off-by: John Bonesio <bones@secretlab.ca> Signed-off-by: Grant Likely <grant.likely@secretlab.ca>
