snd-rn-pci-acp3x - auto dmic detection unreliable

Hi,

it seems that the ACPI auto-detection of the presence the digital microphone connected to AMD Renoir audio bridge is unreliable. It may be that hardware vendors do not provide the correct ACPI tables. Could you clarify the usage of _WOV integer value? It seems that this value is set on those plaforms which do not have the digital microphone (the microphone is connected to the HDA codec):

Lenovo IdeaPad 5 (15ARE05) Lenovo Thinkpad X395

In any case, we should probably improve the auto-detection using DMI or other platform info.
