UPSTREAM: Revert "aarch64: Use cpu_capacity to determine clustering instead"

This reverts commit b7e72de084373e426a9b5de8535d657c27fd99b4.

Reason for revert: It turns out some devices intentionally flattens out their cpu-map topology to improve scheduling behavior. Revert back to using package id to determine clustering info.

Original change's description:
> aarch64: Use cpu_capacity to determine clustering instead
>
> Some systems do not populate cpu-map information and
> use other ways of grouping CPUs in a frequency/topology
> domain instead. Use normalized cpu_capacity information
> to determine clustering instead.

crosvm - The ChromeOS Virtual Machine Monitor

crosvm is a virtual machine monitor (VMM) based on Linux’s KVM hypervisor, with a focus on simplicity, security, and speed. crosvm is intended to run Linux guests, originally as a security boundary for running native applications on the ChromeOS platform. Compared to QEMU, crosvm doesn’t emulate architectures or real hardware, instead concentrating on paravirtualized devices, such as the virtio standard.

crosvm is currently used to run Linux/Android guests on ChromeOS devices.
