ASoC: msm: qdsp6v2: separate multi channel map for playback and record

During concurrency testing scenario which starting multi channel playback
followed by multi channel recording, it was found that channel map of
recording is over written by channel map of playback. This results in
failure to open ADM COPP as wrong channel mapping is being passed.

Separate multi channel map to playback and recording and make explicit
check to decide on which channel map to use during adm open call.
