The device tree is in bid endian format and any properties directly retrieved using OF helpers that don't explicitly byte swap should be annotated. In particular there are several places where we grab the opaque property value for the old ibm,drc-* properties and the ibm,my-drc-index property. Fix this for better static checking by annotating values we know to explicitly big endian, and byte swap were appropriate.
