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.

I would have said 'since these functions are only used in this C file,
make them static'.
I think this could be split in two patches:
1/ Remove unused functions, ie holly_halt() and holly_power_off().
2/ Make the other ones static.

That would be better if it's not too much trouble. A patch with a title
of "Make some functions static" shouldn't really be deleting functions
entirely.

2.20.1
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]
