of/flattree: Update dtc to current mainline.
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>
