DeviceTree for 3.16:

- Another round of clean-up of FDT related code in architecture code.
   This removes knowledge of internal FDT details from most architectures
   except powerpc.
 - Conversion of kernel's custom FDT parsing code to use libfdt.
 - DT based initialization for generic serial earlycon. The introduction
   of generic serial earlycon support went in thru tty tree.
 - Improve the platform device naming for DT probed devices to ensure
   unique naming and use parent names instead of a global index.
 - Fix a race condition in of_update_property.
 - Unify the various linker section OF match tables and fix several
   function prototype errors.
 - Update platform_get_irq_byname to work in deferred probe cases.
 - 2 binding doc updates
