[PATCH v6 02/16] cpu: Do not warn on arch_register_cpu() returning -EPROBE_DEFER

[Jonathan Cameron]

For arm64 the CPU registration cannot complete until the ACPI
interpreter us up and running so in those cases the arch specific
arch_register_cpu() will return -EPROBE_DEFER at this stage and the
registration will be attempted later.
