ASoC: ad193x: Don't power down DAC in CODEC probe
The DAC powerdown bit is managed by DAPM. Manually powering down the DAC in the CODEC probe function may cause unnecessary power state transitions which can lead to click and pop noises. So leave the DAC powerdown bit in its default poweron-reset state and let DAPM do all the management.
