[PATCH] powerpc: include setup.h header file to fix warnings

[Mathieu Malaterre]

Make sure to include setup.h to provide the following prototypes:

- irqstack_early_init
- setup_power_save
- initialize_cache_info

Fix the following warnings (treated as error in W=1):

  arch/powerpc/kernel/setup_32.c:198:13: error: no previous prototype for âirqstack_early_initâ [-Werror=missing-prototypes]
  arch/powerpc/kernel/setup_32.c:238:13: error: no previous prototype for âsetup_power_saveâ [-Werror=missing-prototypes]
  arch/powerpc/kernel/setup_32.c:253:13: error: no previous prototype for âinitialize_cache_infoâ [-Werror=missing-prototypes]
