Subject: [PATCH v2 1/2] powerpc: Make some functions static
Date:   Tue, 26 Mar 2019 21:47:18 +0100

In commit cb9e4d10c448 ("[POWERPC] Add support for 750CL Holly board")
new functions were added. Since most of these functions can be made static,
make it so.

Both holly_power_off and holly_halt functions were not changed since they
are unused, making them static would have triggered the following warning
(treated as error):

  arch/powerpc/platforms/embedded6xx/holly.c:244:13: error: 'holly_halt' defined but not used [-Werror=unused-function]

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]
