mb/ocp/tiogapass: Configure IPMI FRB2 watchdog timer via VPD variables
Add VPD variables for enabling/disabling FRB2 watchdog timer and setting
the timer countdown value in romstage. 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.
Add RO_VPD and RW_VPD sections.
Tested on OCP Tioga Pass.
