cpufreq: powernv: Make some symbols static
The sparse tool complains as follows: drivers/cpufreq/powernv-cpufreq.c:88:1: warning: symbol 'pstate_revmap' was not declared. Should it be static? drivers/cpufreq/powernv-cpufreq.c:383:18: warning: symbol 'cpufreq_freq_attr_cpuinfo_nominal_freq' was not declared. Should it be static? drivers/cpufreq/powernv-cpufreq.c:669:6: warning: symbol 'gpstate_timer_handler' was not declared. Should it be static? drivers/cpufreq/powernv-cpufreq.c:902:6: warning: symbol 'powernv_cpufreq_work_fn' was not declared. Should it be static? Those symbols are not used outside of this file, so mark them static.
