ASoC: AMD Renoir - add DMI entry for Lenovo ThinkPad X395
commit 1f092d1c8819679d78a7d9c62a46d4939d217a9d upstream.
The ThinkPad X395 latop does not have the internal digital
microphone connected to the AMD's ACP bridge, but it's advertised
via BIOS. The internal microphone is connected to the HDA codec.
Use DMI to block the microphone PCM device for this platform.
