Subject: [PATCH 05/13] cpufreq/arch: powerpc: pasemi: Move prototypes to shared header

If function callers and providers do not share the same prototypes the
compiler complains of missing prototypes.  Fix this by moving the
already existing prototypes out to a mutually convenient location.

Fixes the following W=1 kernel build warning(s):

 drivers/cpufreq/pasemi-cpufreq.c:109:5: warning: no previous prototype for ‘check_astate’ [-Wmissing-prototypes]
 109 | int check_astate(void)
 | ^~~~~~~~~~~~
 drivers/cpufreq/pasemi-cpufreq.c:114:6: warning: no previous prototype for ‘restore_astate’ [-Wmissing-prototypes]
 114 | void restore_astate(int cpu)
 | ^~~~~~~~~~~~~~
