Callout support for SBE when watchdog times out
This commit provides additional callout support for SBE when the
host does not respond within watchdog timeout interval during SBE
boot window.
Testing:
Steps used:
1. obmcutil poweroff
2. istep -s0
3. systemctl start org.open_power.Dump.Manager.service
4. systemctl start openpower-debug-collector-watchdog@0.service
5. Check the journal log, and get the PEL id to print PEL info
