cpufreq: CPPC: Remove forward declaration of cppc_cpufreq_register_em()

Browse Source 
cppc_cpufreq_register_em() is only used in populate_efficiency_class(). A
forward declaration of it is not necessary.

Move cppc_cpufreq_register_em() in front of populate_efficiency_class()
and remove the forward declaration of cppc_cpufreq_register_em().

No functional change.
