Bug Description
[SRU Justification]

[Impact]
Audio device fails to function randomly on Intel MTL platform:
```
sof-audio-

```
[Fix]
Proposed fix in upstream commit 26ef47e5ba60 ("ASoC: SOF: ipc4-topology: Add module parameter to ignore the CPC value") that to allow ignoring CPC validation for current fw release.
[Test Case]
1. Boot into OS
2. Check if the internal audio input & output devices work
3. Let system enter suspend, then wake system back up
4. Check if the audio input & output devices work
5. Connect an external audio device (e.g. bluetooth headset, external monitor) and check if they work
6. Disconnect the external audio device
7. Check if the internal audio input & output devices work
8. Reboot system
9. Repeat above steps
[Where problems could occur]
While a 0 CPC value will force the DSP to run at full speed, this is going to impact power consumption until further fix being released for firmware.
[Other Info]
CPC checking landed to v6.5-rc1, so Mantic and oem-6.5 are nominated for fix.

The fix has been included in mainline kernel, but will only be available for 6.6+. Affects mantic 6.5 as well.
