Some server boards like OCP Tiogapass and X11-LGA1151 boards use a gpio for signalling "POST complete" to BMC/IPMI. Add a new driver devicetree option to set the gpio and configure a callback that pulls the gpio low right before jumping to the payload. Test: Check that sensor readings appear in BMC web interface when the payload gets executed. Successfully tested on Supermicro X11SSM-F with CB:48097, X11SSH-TF with CB:48711 and OCP DeltaLake with CB:48672.
