commit e82d70cf965072a3872ea97b7d8df4b6f29fc09f

    powerpc/32: Add missing prototypes for (early|machine)_init()
    
    early_init() and machine_init() have no prototype, add one in
    asm-prototypes.h.
    
    Fixes the following warnings (treated as error in W=1):
      arch/powerpc/kernel/setup_32.c:68:30: error: no previous prototype for ‘early_init’
      arch/powerpc/kernel/setup_32.c:99:21: error: no previous prototype for ‘machine_init’
