mb/supermicro/x11ssm-f: correct trigger for SMI/NMI interrupt inputs
All four SMI/NMI interrupt inputs have an external pull-up resistor and
get triggered by pulling the line low. Thus, correct the trigger to
active-low.
Also document the signals by adding appropriate comments.
The pads' connections have been determined by dissecting a dead board.
