mb/ocp/deltalake: Configure IPMI FRB2 watchdog timer via VPD variables in romstage
Add VPD variables for enabling/disabling FRB2 watchdog timer and setting
the timer countdown value. By default it would start the timer and
trigger hard reset when it's expired. The timer is expected to be
stopped later by payload or OS.
Tested on OCP Delta Lake.
