x86: fix cpu hotplug on 32bit

commit 1ebb854f2bd82514c0ef0e229f75ad265df5ab71 ("x86: boot secondary
cpus through initial_code") causes the kernel to crash when a CPU is
brought online after the read only sections have been write
protected. The write to initial_code in do_boot_cpu() fails.

Move inital_code to .cpuinit.data section.
