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

[Jaroslav Kysela]

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.
