Bug description:
  [SRU Justification]

  [Impact]
  After upgraded the firmware-sof to v2.13.x on Noble for https://bugs.launchpad.net/ubuntu/+source/firmware-sof/+bug/2119516, the ipc4-lib binary files also needs to be copied to the correct path. The system will have DSP panic while loading sof-soundwire driver on Intel LNL platform. There will be no functional audio input/output devices.

  [Fix]
  Only firmware-sof v2.13 on Noble needs to update the signed ipc4-lib binary files for the DSP FW of the Intel LNL platform.
  The firmware-sof on Questing are already in sync with tthe upstream version v2.13.1 which already copy the required ipc4-lib to the correct path.

  [Test Case]

  1. Boot up the laptops powered by Intel LNL platform with sof-soundwire driver
  2. Open settings->Sound->Output Device/Input Device
  3. Check if there's valid input/output device instead of Dummy devices.

  [Where problems could occur]
  The ipc4-lib files are now for Intel LNL platform only and the updated v2.13 ipc4-lib is only for the updated v2.13 DSP FW. No regression expected at the current stage.

  ====================== original bug report ==========================

  [Summary]
  During the machine setup in the lab, I found audio test failure on 2 HP laptops.
  They are hp-elitebook-x-g1i.
