cpufreq/amd-pstate: Set different default EPP policy for Epyc and Ryzen
For Ryzen systems the EPP policy set by the BIOS is generally configured to performance as this is the default register value for the CPPC request MSR. If a user doesn't use additional software to configure EPP then the system will default biased towards performance and consume extra battery. Instead configure the default to "balanced_performance" for this case. Suggested-by: Artem S.
