mb/supermicro/x11ssm-f: configure "POST complete" gpio for IPMI driver
Configure the "POST complete" gpio in the devicetree for the BMC/IPMI driver. Also add the pad to early gpio config, since it has an external pull-up, which is wrong and would confuse the BMC. Set the pad's initial value to zero since the "POST complete" signal is active-high and shall be set by the IPMI/BMC driver. 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.
