On this platform Soundwire Codec RT721 already comes up with DMIC
endpoint. As per our understanding current soundwire topology points to
use RT721 + TI codecs. ACP DMIC is not being used.
If we want to use ACP PDM DMIC where DMIC's are connected to SOC and
routed to ACP PDM controller instead of Soundwire Codec (Which supports
DMIC path), then ACP_PDM_DMIC quirk should be enabled.
