Bug description:
  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.

  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.
