Pull DeviceTree updates from Rob Herring:

 - vsprintf format specifier %pOF for device_node's. This will enable us
   to stop storing the full node names. Conversion of users will happen
   next cycle.

 - Update documentation to point to DT specification instead of ePAPR.

 - Split out graph and property functions to a separate file.

 - New of-graph functions for ALSA

 - Add vendor prefixes for RISC-V, Linksys, iWave Systems, Roofull,
   Itead, and BananaPi.

 - Improve dtx_diff utility filename printing.
