This patch adds support for FSP EPOW (Early Power Off Warning) and
DPO (Delayed Power Off) events for PowerNV platform. EPOW events are
generated by SPCN/FSP due to various critical system conditions that
need system shutdown. Few examples of these conditions are high
ambient temperature or system running on UPS power with low UPS battery.
DPO event is generated in response to admin initiated system request.
  Upon receipt of EPOW and DPO events host kernel invokes
orderly_poweroff for performing graceful system shutdown. System admin
can also add systemd service shutdown scripts to perform any specific
actions like graceful guest shutdown upon system poweroff. libvirt-guests
is systemd service available on recent distros for management of guests
at system start/shutdown time.
