ASoC: SOF: topology: dynamically allocate and store DAI widget->private
For dspless mode, we need to allocate and store an 'sdai' structure. The existing code allocate the data on the stack and does not set the widget->private pointer. This minor change should not have any impact on existing DAIs, even when the DSP is used.
