Add support for audio capture using onboard DMIC. It is directly
connected to vamacro and txmacro without any soundwire interfaces.
The capture was verified using the following commands:
amixer -c0 cset iface=MIXER,name='MultiMedia3 Mixer VA_CODEC_DMA_TX_0' 1
amixer -c0 cset iface=MIXER,name='VA_AIF1_CAP Mixer DEC0' 1
amixer -c0 cset iface=MIXER,name='VA_DEC0 Volume' 110
amixer -c0 cset iface=MIXER,name='VA DMIC MUX0' 2
arecord -D hw:0,2 -f S16_LE -c 2 -r 48000 -d 5 record.wav
