    regulator: Fix display of null constraints for regulators
    
    If the regulator constraints are empty and there is no voltage
    reported then nothing will be added to the text displayed for the
    constraints, leading to random stack data being printed. This is
    unlikely to happen for practical regulators since most will at
    least report a voltage but should still be fixed.
