[PATCH v2 3/3] arm64, topology: enable use of init_cpu_capacity_cppc()

From: Ionela Voinescu <hidden>
Date: 2021-08-24 10:57:14
Also in: linux-acpi, lkml
Subsystem: arm64 port (aarch64 architecture), the rest · Maintainers: Catalin Marinas, Will Deacon, Linus Torvalds

Now that the arch topology driver provides a method of setting CPU
capacity values based on information on highest performance from CPPC,
use this functionality on arm64 platforms.
