ASoC: pcm1789: skip of_device_id table when !CONFIG_OF
The driver can match by multiple methods.  Its of_device_id table is
referenced via of_match_ptr() so it will be unused for !CONFIG_OF
builds:

  sound/soc/codecs/pcm1789-i2c.c:36:34: warning: ‘pcm1789_of_match’ defined but not used [-Wunused-const-variable=]

ASoC: codecs: Add support for PCM1789
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).
