cpufreq: intel_pstate: Update Balance-performance EPP for Granite Rapids
commit 00e2c199cb3780357790852502a74719d14554ec upstream. Update EPP default for balance_performance to 32. This will give better performance out of the box using Intel P-State powersave governor while still offering power savings compared to performance governor. This is in line with what has already been done for Emerald Rapids and Sapphire Rapids.
