Found the solution:

function acf_load_icon_field_choices( $field ) {
    // reset choices
    $field['choices'] = array();
    // get the textarea value from options page without any formatting
    $choices = get_field('icon_values', 'option', false);
    // explode the value so that each line is a new array piece
    $choices = explode("\n", $choices);
    // remove any unwanted white space
    $choices = array_map('trim', $choices);
    // loop through array and add to field 'choices'
    if( is_array($choices) ) {
        foreach( $choices as $choice ) {
            $exploded = explode(' : ', $choice);
            $field['choices'][ $exploded[0] ] = $exploded[1];
          //  $field['choices'][ $choice ] = $choice;
        }
    }
    // return the field
    return $field;
}
add_filter('acf/load_field/name=left_box_icon', 'acf_load_icon_field_choices');
