OSPM evaluates _EVT method to map the event. The cpu hotplug event eventually
results in start of the cpu scan. Scan figures out the cpu and the kind of
event(plug/unplug) and notifies it back to the guest.
The change in this patch updates the GED AML _EVT method with the call to
\\_SB.CPUS.CSCN which will do above.
