drivers/ipmi: implement "POST complete" notification functionality
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.
