For system S5, ACRN had assumption that SOS shutdown will trigger system shutdown. So the system shutdown logical is: 1. Trap SOS shutdown 2. Wait for all other guest shutdown 3. Shutdown system The new logical is refined as: If all guest is shutdown, shutdown whole system Tracked-On: #4270 Signed-off-by: Yin Fengwei <fengwei.yin@intel.com>
