 with dynamic PWM

Subject: fixed builds which weren't using set_level_zero() yet... - emisar-d4
 - emisar-d4v2 - emisar-d4v2-nofet - emisar-d4sv2 - emisar-2ch -
 emisar-2ch-fet - noctigon-dm11-boost - noctigon-k1 - noctigon-kr4 -
 noctigon-kr4-nofet - sofirn-lt1s-pro

... and removed old build targets for d4sv2-tintramp, because it was
replaced by emisar-2ch a while ago.
