driver core: cpu: fix section mismatch in cpu.c:store_online

Browse source 
Fix following warning:
WARNING: vmlinux.o(.text+0x64609c): Section mismatch in reference from the function store_online() to the function .cpuinit.text:cpu_up()

store_online() is defined inside a HOTPLUG_CPU block so references are OK. 
Ignore references by annotating store_online() with __ref.

Note: This is needed because cpu_up() most likely should not have been
__cpuinit but all the hotplug cpu code misuses the __cpuinit annotation.
