Bug description:
  [SRU Justifications]

  ========== linux-firmware ==========
  [Impact]

  Audio output doesn't work on Dell Bolan platforms with CS35L56 speaker
  amplifiers

  [Fix]
  This requires following firmware blobs:
    - https://github.com/CirrusLogic/linux-firmware/commit/367fda8e56d7dda4c138438493e2bf6b9b92ce7b which is not landed in linux-firmware mainline yet.

  [Test Case]
  1. Boot up the machine of Dell Bolan platform with CS35L56 speakers
  2. Verify the sof-lnl-cs42l43-l0.tplg in in the /lib/firmware/intel/sof-ipc4-tplg/
  3. Verify with checking the output of `aplay -l` command with valid sof output device. Should never be dummy output.

  ========== firmware-sof ==========

  [Fix]
  This requires following tplg file in firmware-sof
  - sof-lnl-cs42l43-l0.tplg
  upstream firmware-sof 2.10 will have this tplg file included.

  [Test Case]
  1. Boot up the machine of Dell Bolan platform with CS35L56 speakers
  2. Verify with the linux-firmware with new CS35L56 amplifier support.
  3. Verify with checking the output of `aplay -l` command with valid sof output device. Should never be dummy output.

  
  [Where problems could occur]
  It only affects the Dell Bolan platforms with the new CS35L56 amplifier. Should be low low risk of regression
