NMI (soft reset) control code enablement

Changes here include:
   1) A service that triggers Open BMC App (openpower-proc-nmi)
   2) An application that waits for a dbus event (NMI) to occur
   3) A reset logic that triggers a NMI/softreset dbus service which
      will invoke pdbg call to trigger stop followed by sreset on all
      threads
   4) Necessary Makefile.am changes

Tested: Verified following
 1) openpower-proc-nmi app is automatically started once host is started
 2) After killing the app made sure app is restarted successfully
 3) Verified NMI is detected on the Host side and crash dump being
    collected in /var/crash/ and taking a watchdog triggered reboot
 4) System coming back to original state once all #3 is completed
 5) Powered off the system (obmcutil poweroff) service disabled and
    enabled after host is powered on
