Subject: [PATCH RESEND 4] ARM: plat-versatile: move secondary CPU startup into
 cpuinit


Using __CPUINIT instead of __INIT puts the secondary CPU startup code
into the "right" section: it will not be freed in hotplug configurations,
allowing hot-add of cpus, while still getting freed in non-hotplug configs.

Tested successfully on Fast-Models and on Arndale for VCPU hotplug.
