[PATCH] powerpc/math_emu/efp: Include module.h

[Nathan Chancellor <nathan@kernel.org>]

When building with a recent version of clang, there are a couple of
errors around the call to module_init():

  arch/powerpc/math-emu/math_efp.c:927:1: error: type specifier missing, defaults to 'int'; ISO C99 and later do not support implicit int [-Wimplicit-int]
  module_init(spe_mathemu_init);
  ^
  int
  arch/powerpc/math-emu/math_efp.c:927:13: error: a parameter list without types is only allowed in a function definition
  module_init(spe_mathemu_init);
              ^
  2 errors generated.

module_init() is a macro, which is not getting expanded because module.h
is not included in this file. Add the include so that the macro can
expand properly, clearing up the build failure.

No Fixes tag because it seems likely that this is a transient include
issue (the code builds with GCC). The robot blamed commit e8c07082a810
("Kbuild: move to -std=gnu11") but I think that just exposed these
errors, not caused them.
