The rcar DT overlays are missing symetrical remote-endpoint properties
in their graph nodes because the remote-endpoint is fixed up at
run-time. Disable the dtc 'graph-endpoint' warnings when compiling these
overlays. If this becomes a common problem for overlays, then perhaps
this check needs to be disabled for all overlays.

This needs to go thru my tree because it is dependent on the dtc update 
that adds the warning (perhaps we're going to need to add option 
checking for dtc).
