[PATCH v2] ALSA: hda/realtek: Add quirk for the Framework Laptop

[Dustin L. Howett]

Some board revisions of the Framework Laptop have an ALC295 with a
disconnected or faulty headset mic presence detect.

The "dell-headset-multi" fixup addresses this issue, but also enables an
inoperative "Headphone Mic" input device whenever a headset is
connected.

Adding a new quirk chain specific to the Framework Laptop resolves this
issue. The one introduced here is based on the System76 "no headphone
mic" quirk chain.

The VID:PID f111:0001 have been allocated to Framework Computer for this
board revision.

Revision history:
- v2: Moved to a custom quirk chain to suppress the "Headphone Mic"
  pincfg.
