cpufreq: amd-pstate: enable shared memory type CPPC by default

Browse source

The amd-pstate-epp driver has been implemented and resolves the
performance drop issue seen in passive mode for shared memory type
CPPC systems. Users who enable the active mode driver will not
experience a performance drop compared to the passive mode driver.
Therefore, the EPP driver should be loaded by default for shared
memory type CPPC system to get better performance.
