Bug description:
  [Impact]
  Dell Renegade laptops come with Cirrus smart amplifier have inconsistent 
volume issue on left/right speaker. Speaker will output from both channels even 
we only expect output from single channel. It needs the updated tuning files in 
linux-firmware.

  [Fix]
  Backport the fix from 5be0792a ("cirrus: cs35l56: Add firmware for Cirrus 
CS35L56 for various Dell laptops") on linux-firmware.

  [Test Case]
  1. Boot up the Dell Renegade laptops.
  2. Open settings->Sound->Output Device
  3. Click test icon to separately test the left and right speaker
  4. Verify the sound output volume by ear from left speaker and right speaker.

  [Where problems could occur]
  It updated tuning files for specific Dell platforms by SSIDs. No regression 
expected at the current stage.
