pwm: rockchip: Don't update the state for the caller of pwm_apply_state()
The pwm-rockchip driver is one of only three PWM drivers which updates
the state for the caller of pwm_apply_state(). This might have
surprising results if the caller reuses the values expecting them to
still represent the same state.
