Zen6 client platforms use CPPC differently than previous platforms and knowing maximum frequency for a core type is needed for capacity calculations. Newer versions of the ACPI will introduce a proper interface for getting this information, but for now hardcode values so that these systems perform as intended and to unblock future scheduler work while we continue to wait.
