Bug Description

[Impact]
On the machine of Lenovo M715, there are 2 audio jacks on the front panel,
one of them is microphone jack. When we plug a micrphone into it, the system
can't detect this microphone and can't record sound via this microphone too.

[Fix]
Apply the quirk of ALC294_FIXUP_LENOVO_MIC_LOCATION, the alsa driver will
assign a different name to this audio jack, then pulseaudio can handle this
jack and everything works well.

[Test Case]
plug a microphone to this jack and record sound, system can detect the
microphone and can record sound.

[Regression Potential]
Very low, this pin configuration is specific to the machine of
M715 so far, will not affect other machines.
