cpufreq: intel_pstate: Update Balance-performance EPP for Granite Rapids

Browse Source 
BugLink: https://bugs.launchpad.net/bugs/2097554

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.
