mb/ocp/deltalake: replace "POST complete" mb code with driver functionality

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.

Tested successfully.
