[U-Boot] [PATCH] zynq: disable -Wstrict-prototypes option for ps7_init.c

[U-Boot] [PATCH] zynq: disable -Wstrict-prototypes option for ps7_init.c

[Masahiro Yamada]

The files ps7_init.c and ps7_init.h are supposed to be generated by
hw projects such as Vivado, PlanAhead and then to be copied into
board/xilinx/zynq directory.

But some prototypes in them causes annoying warning messages:

  CC      spl/board/xilinx/zynq/ps7_init.o
In file included from board/xilinx/zynq/ps7_init.c:50:0:
board/xilinx/zynq/ps7_init.h:137:1: warning: function declaration isn't a prototype [-Wstrict-prototypes]
board/xilinx/zynq/ps7_init.h:138:1: warning: function declaration isn't a prototype [-Wstrict-prototypes]

board/xilinx/zynq/ps7_init.c:12854:6: warning: function declaration isn't a prototype [-Wstrict-prototypes]

The prototypes should be

  int ps7_init(void);
  int ps7_post_config(void);
  int ps7_debug(void);

rather than

  int ps7_init();
  int ps7_post_config();
  int ps7_debug();

We do not want to be bothered because of automatically generated files.
But we cannot touch the external projects for now.
What we can do is to disable -Wstrict-prototypes for ps7_init.c
