Subject: [PATCH] Tools: Topology2: Add SRC component to cavs-nocodec.conf
 topologies

This patch adds 8 - 192 kHz playback and capture SRC to nocodec
topologies such sof-tgl-nocodec.tplg. It enables testing of SRC
component with IPC4 via the SSP loopback in the nocodec topologies

E.g. Play random noise at 44.1 kHz and capture it as 32 kHz. The
SSP loopback runs internally at 48 kHz.

aplay -Dhw:0,2 -f S32_LE -c 2 -r 44100 -d 10 -t raw /dev/random
arecord -Dhw:0,2 -f S16_LE -c 2 -r 32000 -d 10 /tmp/recording.wav
