[PATCH 2/2] cpufreq: intel_pstate: Update default EPPs for Meteor Lake

[Srinivas Pandruvada]

Update default balanced_performance EPP to 115 and performance EPP to 16.

Changing the balanced_performance EPP has better performance/watt
compared to default powerup EPP value of 128.

Changing the performance EPP to 0x10 shows reduced power for similar
performance as EPP 0. On small form factor devices this is beneficial
as lower power results in lower CPU and skin temperature. This
results in reduced thermal throttling and higher performance.
