    base-files: get_dt_led: don't warn about missing led
    
    It's intentional that some boards within a target don't have all LEDs
    which are tried to be setup in a common script. Don't show a warning in
    such cases.
    
    Fixes: 4f4fc993db4c ("base-files: add more name source to get_dt_led helper function")
