      trivial:

      fdt_support.c:352:65: warning: Using plain integer as NULL pointer
      
      For the following bad constant expression, We hardcode the max. number of
      memory banks to four for the foreseeable future, and add an error with
      instructions on what to do once it's exceeded:
      
      fdt_support.c:397:22: error: bad constant expression
      
      For the rest below, sparse found a couple of wrong endian conversions
      in of_bus_default_translate() and fdt_get_base_address(), but
      otherwise the rest is mostly annotation fixes:
