/*
* Here add one platform module "imx-pcm-asrc" as pcm platform module.
* If we use the asrc_p2p node as the pcm platform, there will be one issue.
* snd_soc_dapm_new_dai_widgets will be called twice, one in probe link_dais,
* one in probe platform. so there will be two dai_widgets added to widget list.
* but only the seconed one will be recorded in dai->playback_widget.
* Machine driver will add the audio route, but when it go through the
* widget list, it will found the cpu_dai widget is the first one in the list.
* add use the first one to link the audio route.
* when use the fe/be architecture for asrc p2p, it need to go through from
* the fe->cpu_dai->playback_widget. but this is the second widget, so the
* result is that it can't find a availble audio route for p2p case. So here
* use another pcm platform to avoid this issue.
