Bug description:
SRU Justification:

[Impact]
New Dell platform with Realtek codec ALC3329B+ALC1708B powered by Intel PantherLake will have no basic audio functions w/o Soundwire Driver Support.

================ Linux Kernel ========================

[Fix]
Backport new Intel soundwire drivers of the following
ASoC: sof-function-topology-lib: escalate the log when missing function topoplogy - kernel/git/broonie/sound.git - ASoC
ASoC: SOF: Intel: use sof_sdw as default SDW machine driver - kernel/git/broonie/sound.git - ASoC
ASoC: SOF: add platform name into sof_intel_dsp_desc - kernel/git/broonie/sound.git - ASoC
ASoC: soc_sdw_utils: export asoc_sdw_get_dai_type - kernel/git/broonie/sound.git - ASoC
ASoC: Intel: export sof_sdw_get_tplg_files - kernel/git/broonie/sound.git - ASoC
ASoC: soc_sdw_utils: add name_prefix to asoc_sdw_codec_info struct - kernel/git/broonie/sound.git - ASoC
ASoC: soc-acpi: make some variables of acpi adr and link adr non-const - kernel/git/broonie/sound.git - ASoC
ASoC: SOF: Don't print the monolithic topology name if function topology may be used - kernel/git/broonie/sound.git - ASoC
ASoC: SOF: don't check the existence of dummy topology - kernel/git/broonie/sound.git - ASoC

and ALC3329B+ALC1708B from Realtek

ASoC: rt722: add settings for rt722VB - kernel/git/broonie/sound.git - ASoC
ASoC: rt1321: Add RT1321 amplifier support - kernel/git/broonie/sound.git - ASoC
ASoC: rt712: avoid skipping the blind write - kernel/git/broonie/sound.git - ASoC
ASoC: sdw_utils: add rt1321 part id to codec_info_list - Patchwork
ASoC: sdw_utils: add name_prefix for rt1321 part id - kernel/git/broonie/sound.git - ASoC
ASoC: SOF: Intel: add hyphen between name and index to amp name_prefix - kernel/git/broonie/sound.git
ASoC: SOF: don't check the existence of dummy topology - kernel/git/broonie/sound.git - ASoC

=============== linux-firmware ========================

[Fix]
Backport the patch firmware from Realtek
realtek: rt1321: Add patch firmware of MCU - kernel/git/firmware/linux-firmware.git - Repository of firmware blobs for use with the Linux kernel

=============== alsa-ucm-conf ========================

[Fix]
Backport the patch

and

PR (https://github.com/alsa-project/alsa-ucm-conf/pull/628
[github.com])

 from upstream

[Test Case]
1. Boot up the machine of new Dell Intel PantherLake platform with Realtek ALC3329B+ALC1708B.
2. Open settings->Sound->Output Device and make sure it's not Dummy audio devices
3. Click test icon for basic audio output functions
4. Use `arecord` to record and play the recorded audio file with `aplay` for basic speaker/microphone functions.

[Where problems could occur]
It adds the support for new Realtek codec+amplifier on PTL platform. No regression expected at the current stage.
