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.
