Subject: [PATCH v2 15/21] powerpc: Make function MMU_setup static

Since function `MMU_setup` is not meant to be exported, change the
signature to `static`. Fix warning (treated as error with W=1):

  CC      kernel/sys.o
arch/powerpc/mm/init_32.c:102:13: error: no previous prototype for ‘MMU_setup’ [-Werror=missing-prototypes]
 void __init MMU_setup(void)
             ^~~~~~~~~
cc1: all warnings being treated as errors
