cpufreq: intel_pstate: Eliminate some code duplication

Browse Source 
To eliminate some code duplication from the intel_pstate driver,
move the core_get_val() function body to a new function called
get_perf_ctl_val() and make both core_get_val() and atom_get_val()
invoke it to carry out the same computation.

No intentional functional impact.
