ARM: report present cpus instead of online CPUs
For machines that use hotplug to control special power domains, report
present cpus in /proc/cpuinfo and /proc/stat instead of the standard of
reporting online. This break hotplug behavior on all other platforms.
The option is enabled using CONFIG_REPORT_PRESENT_CPUS
