[PATCH] powerpc/wii: Make hlwd_pic_init function static

[Mathieu Malaterre]

The function hlwd_pic_init can be made static, so do it. Fix the following
warning treated as error (W=1):

../arch/powerpc/platforms/embedded6xx/hlwd-pic.c:158:20: error: no previous prototype for âhlwd_pic_initâ [-Werror=missing-prototypes]
