 Chinchou/Chinchou360 Chromebooks

Without `compatible` override:

```
chinchou360-rev1 ~ # dmesg | grep mt8186_mt6366
[    8.998560] mt8186_mt6366 sound: ASoC: Parent card not yet
available, widget card binding deferred
[    9.020741] mt8186_mt6366 sound: ASoC: Failed to add route

snd_soc_dapm_add_routes failed: -19
[    9.070269] mt8186_mt6366 sound: error -ENODEV: Cannot register card
```

With `compatible` override:
```
[    9.110380] mt8186_mt6366 sound: ASoC: Parent card not yet
available, widget card binding deferred
[    9.131681] mt8186_mt6366 sound: ASoC: driver name too long

```
