colibri_t20: fix reset out pin

Make sure SODIMM pin 87 nRESET_OUT is released properly by explicitly
setting its pin mux function to GMI. This solves some issues with e.g.
USB not being fully operational on carrier boards with USB hubs
connected to reset if U-Boot got loaded via recovery mode aka rcm.
