mb/ocp/tiogapass: use IPMI driver functionality for "POST complete"
Replace the mainboard-specific code for "POST complete" signalling with
devicetree entries for using the newly introduced IPMI driver
functionality.
Test: Boot the machine via the BMC web interface and check that sensors
get read correctly by the IPMI firmware when the payload starts.
