Pull DeviceTree updates from Rob Herring:
"Pretty standard stuff with dtc upstream sync being the biggest piece.
- Sync dtc to upstream commit 0931cea3ba20. This picks up overlay
support in dtc.
- Set dma_ops for reserved memory users.
- Make references to IOMMU consistent in DT bindings.
- Cleanup references to pm_power_off in bindings.
- Move some display bindings that snuck into the old bindings/video/
path.
- Fix some wrong documentation paths caused from binding
restructuring.
- Vendor prefixes for Faraday and Fujitsu.
- Fix an of_node ref counting leak in of_find_node_opts_by_path
- Introduce new graph helper of_graph_get_remote_node() which will be
used by DRM drivers in 4.12"
