cpufreq/amd-pstate: Cache EPP value and use that everywhere
Cache the value in cpudata->epp_cached, and use that for all callers.
As all callers use cached value merge amd_pstate_get_energy_pref_index()
into show_energy_performance_preference().
Check if the EPP value is changed before writing it to MSR or
shared memory region.
