alsa: front mics could not work on a couple of Lenovo ThinkCenter machines

[Hui Wang]

This patch is cced to stable kernel, so it will be merged to other
ubuntu kernels automatically, and because the oem project schedule, we
need to merge this patch to oem-5.6 first.

[Impact]
There are 2 front mic on those lenovo thinkcenter machines, but all
front mics can't work.

[Fix]
change the location for one of the mics, then pulseaudio could handle
them.

[Test Case]
Boot the kernel with this patch, plug microphone/headset to either
front mic jack, the mic could be detected and could record the sound.

[Regression Risk]
Low, just adding a new pintbl to match those lenovo machines.
