Some boards like Gen7 have a power on pin, to enable the ATX power supply. If this is defined,
the power will be turned on without the need to call M80 if initially started.
0 = Do not power on
1 = Power on startup
2 = Only power on when heaters / heatbed target temp >= 20 and power off again when heaters & heatbed all off (or on sensor defect)
