optimized default EPP for GNR family

[Thibault Ferrante]

[ Impact ]

 * Update EPP default for balance_performance to 32. This will give
   better performance out of box using Intel P-State powersave governor
   while still offering power savings compared to performance governor.
 * Improvement of ~10% on perf per/watt.

[ Fix ]

 * Clean cherry-pick from upstream:
   00e2c199cb378 cpufreq: intel_pstate: Update Balance-performance EPP for Granite Rapids

[ Test Plan ]

 * Compiled and tested by intel.

[ Where problems could occur ]

 * Performance or powersaving regression.
