Add Texas Instruments's PCM1789 DAC support. It is a simple DAC and does not have many registers. One particularity about this DAC is that the clocks must be always enabled. Also, an entire software reset is necessary while starting to play a sound otherwise, the clocks are not synchronized (so the DAC is not able to send data).
