stm32: fix DAC examples

The DAC driver defaults to enabling the channel trigger, but leaves it
at the default value of TIM6 TRGO, then performs a software trigger
after writing the new output value. We could change the trigger
selection to software trigger, but for this example it's simpler to just
disable the trigger.
