Increase sound-dai-cells to 1 to allow using the DAIs in the codec corresponding to AIF2 and AIF3. The generic ASoC OF code supports a #sound-dai-cells value of 0 or 1 with no impact to the driver, so this is a backward-compatible change.

A value of 0 is deprecated. When used, it only allows access to

the ADC/DAC and AIF1 (the CPU DAI), not the other two AIFs/DAIs.
