Only send this patch to oem-5.6 kernel, and after this patch is
merged to stable kernel, this patch will be merged to the rest
ubutnu kernels.

On a Lenovo ThinkCenter, there are 2 front mics, but the pulseaudio
could handle it, so the front mics could not work.

Apply an existing quirk to change the location for one of the mics.

[Test Case]
Plug the mic or headset to either front mic jacks, all work well.

[Regression Risk]
Low, it is specific to a lenovo machine.
