[Impact]
RT712 on Intel LNL of Thinkpad failed to detect headset plugin.

[Fix]
Add MIPI-specific property_read_bool() helpers to check
the value extracted from platform firmware.

https://github.com/thesofproject/linux/issues/5129

[Test]
Tested on Intel LNL and MTL, the headset jack detection works fine.

[Where problems could occur]
It may break Intel soundwire.

Plucky got this fix on 6.13-rc1.
