ASoC: simple-card-utils: share dummy DAI and reduce memory
Current simple-card / audio-graph creates 1xCPU + 1xCodec + 1xPlatform for all dai_link, but some of them is not needed. For example Platform is not needed for DPCM BE case. Moreover, we can share snd-soc-dummy DAI for CPU-dummy / dummy-Codec in DPCM. This patch adds dummy DAI and share it when DPCM case, I beliave it can contribute to reduce memory. By this patch, CPU-dummy / dummy-CPU are set at asoc_simple_init_priv(), thus, its settings are no longer needed at DPCM detecting timing on simple-card / audio-graph. Moreover, we can remove triky Platform settings code for DPCM BE, because un-needed Platform is not created.
