[Impact]
On one of Lenovo thinkcenter machines we have, there are two microphone jacks
on the front panel, but only one of them can work after we plug a micrphone in
them.

[Fix]
Because two microphones are located in front panels, the alsa driver will assign
the same jack name to them, but pulseaudio can't handle two jacks with the same
name.

After applying this FIXUP, they will have different mixer name,
then pulseaudio can handle them correctly.


[Test Case]
After booting up, plug micrphone into any one of the two audio jacks, the microphone
works very well.

[Regression Potential]
Very low, since this patch is specific to the thinkcenter machine with subsystem id
0x17aa3138.
