asoc: msm-pcm-routing: add support for a2dp echo ref

Browse Source 
Add support for a2dp echo reference for SVA. This is
used to cancel a2dp playback echo from voice activation
input samples.
When phone connects to A2DP speaker like car kit,
selecting A2DP as echo reference can have better VA
performance.
