Bug description:
  [Impact]
  The headset couldn't work on M70/M90 Gen4 on 6.1.0-oem kernel and 5.19 
generic kernel.
  Lenovo M70/M90 Gen4 are equipped with ALC897, and they need
  ALC897_FIXUP_HEADSET_MIC_PIN quirk to make its headset mic work.
  The previous quirk for M70/M90 is for Gen3.

  [Fix]
  cherry picked from commit 4ca110cab46561cd74a2acd9b447435acb4bec5f

  [Test]
  After applying the patch, the os works fine with the headset mic on 6.1.0-oem.

  [Where problems could occur]
  It's just a quirk for sound/pci/hda/patch_realtek.c, the risk is low.
