Subject: [PATCH] powerpc: Make some functions static

In commit cb9e4d10c448 ("[POWERPC] Add support for 750CL Holly board")
new functions were added. Since these functions can be made static,
make it so. While doing so, it turns out that holly_power_off and
holly_halt are unused, so remove them.

Silence the following warnings triggered using W=1:

  arch/powerpc/platforms/embedded6xx/holly.c:47:5: error: no previous prototype for 'holly_exclude_device' [-Werror=missing-prototypes]
  arch/powerpc/platforms/embedded6xx/holly.c:190:6: error: no previous prototype for 'holly_show_cpuinfo' [-Werror=missing-prototypes]
  arch/powerpc/platforms/embedded6xx/holly.c:196:17: error: no previous prototype for 'holly_restart' [-Werror=missing-prototypes]
  arch/powerpc/platforms/embedded6xx/holly.c:236:6: error: no previous prototype for 'holly_power_off' [-Werror=missing-prototypes]
  arch/powerpc/platforms/embedded6xx/holly.c:243:6: error: no previous prototype for 'holly_halt' [-Werror=missing-prototypes]
