mb/supermicro/x11ssh-tf: configure "POST complete" gpio for IPMI driver

Configure the "POST complete" gpio in the devicetree for the BMC/IPMI
driver and set the pad's initial value to 0 since the signal is active-
high and shall be set by the IPMI/BMC driver.

Also add the pad to early gpio config, since it is expected to have an
external pull-up like X11SSM-F, which is wrong and would confuse the BMC.

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.
