[AceLan Kao]

[Impact]
On the development, we found sometimes there is no audio output device
when headphone is connected to the rear audio jack.

[Fix]
Cirrus Logic provides a patch to fix this
https://patchwork.kernel.org/project/alsa-devel/patch/20221205145713.23852-1-vitalyr@opensource.cirrus.com/

The patch has been accepted but still not shown in the upstream tree,
so submit this patch to oem kernels first, and will submit it to other
generic ubuntu kernels.

[Test]
Verified by our QA and ODM.

[Where problems could occur]
It extends the delay time, should be no harm for existing platforms.

    settle and lock.
