Add the new DAPM audio map audio_map_asrc used with the dummy codec.
The dummy codec doesn't have any Playback or Capture DAPM widgets. DAPM
default audio maps are thus unused with it. However, when using the
ASRC, DAPM routes between CPU DAI and ASRC are still required.
The driver must then handle this use case.
