LoongArch: convert to use arch_cpu_is_hotpluggable() 

mainline inclusion
from mainline-v6.8-rc1
commit 13f9f0361c2e64f0dadb7964bfad11bf0a6fb7ab
category: feature
bugzilla: https://gitee.com/openeuler/kernel/issues/I8XMTL


CVE: NA

----------------------------------

Convert loongarch to use the arch_cpu_is_hotpluggable() helper rather
than arch_register_cpu(). Also remove the export as nothing should be
using arch_register_cpu() outside of the core kernel/acpi code.
