No need for Plucky since the latest 1.2.12 already contains the fix

[SRU Justifications]
========== alsa-ucm-conf ==========
[Impact]
Audio output doesn't work on Dell Tarako platforms with Cirrus CS42L43
codec
[Fix]
This requires following conf file in alsa-ucm-conf package:
- /usr/share/alsa/ucm2/sof-soundwire/cs42l43-spk.conf
[Test Case]
1. Boot up the machine of Dell Bolan platform with CS42L43 codec
2. Verify the existence of /usr/share/alsa/ucm2/sof-soundwire/cs42l43-spk.conf
3. Verify with checking the output of `amixer -c 0` command with valid
Digital Speaker `Simple mixer control 'cs42l43 Speaker Digital',0`.
[Where problems could occur]
It only affects the Dell Tarako platforms with the new CS42L43 codec w/o
other soundwire devices. Should be low low risk of regression
========== firmware-sof ==========
[Fix]
This requires following tplg file in firmware-sof
- - sof-lnl-cs42l43-l0.tplg
- upstream firmware-sof 2.11 will have this tplg file included.
+ - sof-lnl-cs42l43-l0.tplg and sof-arl-cs42l43-l0.tplg
+ upstream firmware-sof 2.11.x will have these tplg file included.
[Test Case]
- 1. Boot up the machine of Dell Tarako platform with cs42l43 internal speakers
+ 1. Boot up the machine of Dell Tarako LunarLake and ArrowLake platform with
cs42l43 internal speakers
2. Verify with checking the output of `aplay -l` command with valid sof
output device. Should never be dummy output.
[Other Info]
The name of sof-lnl-cs42l43-l0.tplg includes useful information which
indicates that the topology is for for the cs42l43 codec connected to soundwire
bus 0 w/o other soundwire devices connected on 1/2/3. It only affects the
machines which has exactly the same soundwire configuration. The upstream
commit of a newer version usually include the topology files for the new
platforms or missing configuration on old platforms. It would be better to
catch up with upstream to have these configuration which can support more
configurations we could be missing in the future. The the addtional
0002-Add-SOF-v2.11.1-signed-Intel-binaries-for-MTL-LNL-AR.patch, it's required
for each new Intel Platform and signed by Intel. In the case, the tplg file
specify the `lnl`, a signed LunarLake DSP FW will be necessary. It would be
better to have the Intel signed DSP FW up-to-date.
[Where problems could occur]
Although there're lots of new tplg files added, but they are mostly for
missing configuration on old platforms or newly added for next-gen Intel
platform. And they are specified for particular soundwire configurations which
can hardly affect the existing machines. The risk for regression may come from
sof-hda-generic-xxx.tplg which is for generic HDA. I'll consider it as low risk.
