4.2 Voltage Regulator Watchdog Timer Sensor

The BMC FW monitors that the power sequence for the board VR controllers is completed when a DC power-on is initiated.
Incompletion of the sequence indicates a board problem, in which case the FW powers down the system.

The sequence is as follows:

 BMC FW monitors the PowerSupplyPowerGood signal for assertion, indicating a DC-power-on has been initiated, and starts a

timer (VR Watchdog Timer). For EPSD Platforms Based on Intel
