cpu: fix section mismatch warning in reference to register_cpu_notifier
Fix following warnings: WARNING: vmlinux.o(.text+0xc60): Section mismatch in reference from the function kvm_init() to the function .cpuinit.text:register_cpu_notifier() WARNING: vmlinux.o(.text+0x33869a): Section mismatch in reference from the function xfs_icsb_init_counters() to the function .cpuinit.text:register_cpu_notifier() WARNING: vmlinux.o(.text+0x5556a1): Section mismatch in reference from the function acpi_processor_install_hotplug_notify() to the function .cpuinit.text:register_cpu_notifier() WARNING: vmlinux.o(.text+0xfe6b28): Section mismatch in reference from the function cpufreq_register_driver() to the function .cpuinit.text:register_cpu_notifier() register_cpu_notifier() are only really defined when HOTPLUG_CPU is enabled. So references to the function are OK. Annotate it with __ref so we do not get warnings from callers and do not get warnings for the functions/data used by register_cpu_notifier().
