Bug description:
[SRU Justifications]
[Impact]
Dell Renegade comes with Cirrus cs42l43 codec + cs35l56 amplifier on
Intel ARL platform. It requires the latest driver fix from Cirrus on
to have audio functions working correctly.
[Fix]
Backport the patches to support the cs35l56 amplifier on sdw link 2/3.
1.
https://git.kernel.org/pub/scm/linux/kernel/git/broonie/sound.git/commit/?id=a3003af649efb6f3d86d379d1e9a966ea6d5f5ab

[Test Case]
1. Boot up the Dell Renegade laptops.
2. Make sure firmware-sof, alsa-ucm-conf and kernel version support Cirrus
codec. (alsa-ucm-conf needs to be >= 1.2.10-1ubuntu5.4, firmware-sof >=
2023.12.1-1ubuntu1.3)
3. check with the `aplay -l` commands to see if any valid audio output
devices.
4. Make sure the audio play/record function is working.
[Where problems could occur]
It add support the CS42L43 + CS35L56 configuration on Intel ARL platform and
the CS35L56 on sdw bus link 2 and 3 which need new firmware-sof and
alsa-ucm-conf to support. Only affects machines with the same audio
configuration. The risk of regression is low.
