Tools: Topology: Add to nocodec port2 24 kHz rate capability

[singalsu]

This patch adds the 24 kHz rate to PCM capabilities. The 24 kHz rate is defined in the MPEG-2 standard. This also needs a patch to alsa-lib to build the topology without error.

The added rate_min/rate_max is not mandatory but it narrows down the range of rates evaluated in alsa-lib in snd_pcm_hw_refine().

[singalsu]

From Jenkins build log here, need the alsa-lib patch:

[9/372] Generating sof-tgl-nocodec.tplg
ALSA lib pcm.c:366:(split_rate) unsupported stream rate 24000
ALSA lib parser.c:211:(tplg_load_config) failed to parse topology
Unable to load configuration: Invalid argument

[singalsu]

LGTM, I guess you will make non draft when ALSA part is resolved.

Yep, this simple add only enables tplg build, the aplay - alsa-lib - kernel runtime issue still remains:
