[RFC PATCH 05/32] drivers: base: Move cpu_dev_init() after node_dev_init()

From: James Morse <james.morse@arm.com>

Also in: kvm, kvmarm, linux-acpi, linux-arch, linux-pm, lkml, loongarch
Subsystem: driver core, kobjects, debugfs and sysfs, the rest · Maintainers: Greg Kroah-Hartman, "Rafael J. Wysocki", Danilo Krummrich, Linus Torvalds

NUMA systems require the node descriptions to be ready before CPUs are
registered. This is so that the node symlinks can be created in sysfs.

Currently none of these platforms use GENERIC_CPU_DEVICES, meaning
that CPUs aren't registered by cpu_dev_init().

Move cpu_dev_init() after node_dev_init() so that NUMA architectures
can use GENERIC_CPU_DEVICES.
