macintosh/via-pmu: Make some symbols static
The sparse tool complains as follows:
drivers/macintosh/via-pmu.c:183:5: warning:
symbol 'pmu_cur_battery' was not declared. Should it be static?
drivers/macintosh/via-pmu.c:190:5: warning:
symbol '__fake_sleep' was not declared. Should it be static?
These symbols are not used outside of via-pmu.c, so this
commit marks them static.
