platform_cpu_die() is entered from the CPU's own idle thread, which
can not be migrated to other CPUs. Moreover, the 'cpu' argument
comes from the thread info, which will always be the 'current'
CPU. So remove this useless bug check.

We always need to wait for the dying CPU to reach a safe state before
taking it down, irrespective of the requirements of the platform.
Move the completion code into the ARM SMP hotplug code rather than
having each platform re-implement this.

This patch adds cpu hotplug support for OMAP4430. Only CPU inactive
state is supported as a low power state in the basic hot-plug support
