[ARM] Fix breakage caused by 72486f1f8f0a2bc828b9d30cf4690cf2dd6807fc

72486f1f8f0a2bc828b9d30cf4690cf2dd6807fc inverted the sense for
enabling hotplug CPU controls without reference to any other
architecture other than i386, ia64 and PowerPC.  This left
everyone else without hotplug CPU control.

Fix ARM for this brain damage.
