Fix following warnings:

function take_cpu_down() to the variable .cpuinit.data:cpu_chain

WARNING: vmlinux.o(.text+0x75de4): Section mismatch in reference from the

WARNING: vmlinux.o(.text+0x75e33): Section mismatch in reference from the
function _cpu_down() to the variable .cpuinit.data:cpu_chain
cpu_down is only used from code surrounded by HOTPLUG_CPU
so any references to __cpuinit is OK.
Add a few __ref to tech modpost to ignore the references.
This is just papering over the fact that the cpu hotplug
code is fragile with respect to use of HOTPLUG_CPU and
in many cases rely on __cpuinit to get rid of code
when HOTPLUG_CPU is not enabled.
For now this is the least invasive change.
