Log:
  MFC r322287 (mw): Add support for "compatible" parameter in ofw_fdt_fixup
  
  Sometimes it's convenient to provide fixup to many boards
  that use the same SoC family (eg. Marvell Armada 38x).
  Instead of putting multiple entries in fdt_fixup_table,
  use one entry which refers to all boards with given SoC.
