Alexey Brodkin a3cde14f5a arc: use patched .dts from sources
Instead of using off-the-tree .dts files for ARC boards we're
switching to use in-tree ones. And for that to work properly
we apply upstream patch that adds currently missing "model"
property.

Upstream patch and discussion could be found here:
