In atmel_pctl_dt_subnode_to_map(), the return value of pinctrl_utils_add_map_mux() needs to be checked, for the function will fail to associate group when the group map is full. Add error handling for pinctrl_utils_add_map_mux() to return immediately and propagate the error code to caller function when the function fails.
