Factor out duplicated code for hotplug

Registered by Daniel Lezcano on 2013-05-06

The code is duplicated in the different arch/arm/mach-*/hotplug.c
Also, the WFI function looks weird: investigate the replacement with the cpu_do_idle function.

Despite what it looks like, the code across, the different SoC, could be much more different than what it appears. The code is resulting of multiple copy'n paste.

Russell King clearly describe the differences and it is not worth to go further for now in the code consolidation around this area.
