Architectures often have extra per-cpu work that needs doing
before a CPU is registered, often to determine if a CPU is
hotpluggable.
To allow the ACPI architectures to use GENERIC_CPU_DEVICES, move
the cpu_register() call into arch_register_cpu(), which is made __weak
so architectures with extra work can override it.
This aligns with the way x86, ia64 and loongarch register hotplug CPUs
when they become present.

Changes since RFC:
* Dropped __init from x86/ia64 arch_register_cpu()
Changes since RFC v2:
* Dropped unnecessary Loongarch asm/cpu.h changes
