Pull devicetree changes from Grant Likely:
 "Here are the devicetree changes queued up for v4.1.  Nothing really
  exciting here.  Rob has another few commits for big-endian attached
  UARTs, but those will be sent in a separate merge request since they
  haven't been as thoroughly tested as this batch.

  Here are the highlights:

   - lots of unittest cleanup from Frank Rowand

   - bugfixes and updates to the of_graph code

   - tighten up of_get_mac_address() code

   - documentation updates"
