ACPI: CPPC: Add AMD pstate energy performance preference cppc control
Add support for setting and querying EPP preferences to the generic
CPPC driver. This enables downstream drivers such as amd-pstate to discover
and use these values.
Downstream drivers that want to use the new symbols cppc_get_epp_caps
and cppc_set_epp_perf for querying and setting EPP preferences will need
to call cppc_set_epp_perf to enable the EPP function firstly.
