Bug description:
[SRU Justifications]
========== linux ==========
[Impact]
Lenovo ThinkPad comes with Realtek RT713 codec + RT1318 amplifier on
Intel LNL platform. It needs the latest driver from Realtek on alsa-
ucm-sof and kernel to have LED function working correctly.
========== alsa-ucm-conf ==========
We still need wait a while for all the patches in upstream.

https://github.com/alsa-project/alsa-ucm-conf/pull/512/
https://github.com/alsa-project/alsa-ucm-conf/pull/525/
[Test Case]
1. Boot up the ThinkPad X1 Carbon Gen13 laptops.
2. Make sure alsa-ucm-conf and kernel version support RT713+RT1318.
3. Make sure the LED of speaker and mic is working.
[Where problems could occur]
UCM2 add support the RT713+RT1318 configuration on Intel LNL platform. Also
need kernel's patch to support. No regression expected at the current stage.
