ENGR00218774 ESAI ASRC: fix multi channel p2pplayback bug
ASRC driver would configure ASRC as ideal ratio mode for p2p playback.
However, multi channel convert can't work well with ideal ratio mode.
In this patch, change ASRC p2p playbck mode to internal ratio mode to
better support multi channel p2p playback.
