As per PAPR specification whenever system is running on UPS we have to
wait for predefined time (default 10mins) before initiating shutdown.
We have user space tool (rtas_errd) to monitor for EPOW events and
initiate shutdown after predefined time. Hence do not initiate shutdown
whenever we get EPOW_SHUTDOWN_ON_UPS event.
Fixes: 79872e35 (powerpc/pseries: All events of EPOW_SYSTEM_SHUTDOWN must initiate shutdown)
