[Impact]
No audio input or output on ThinkPad P1 or P16.

[Fix]
Add sof-bin, linux-firmware and kernel commits to support it.

sof-bin:
c2c74b7 v2.13.x: Update v2.13.1 new/updated topology files

linux-firmware:
c6a9ced6 cirrus: cs35l56: Add firmware for Cirrus Amps for some Lenovo laptops

kernel commits:

a7528e9beadbd ASoC: Intel: soc-acpi: arl: Correct order of cs42l43 matches

[Test]
Steps:
1, hear the sound from
$ speaker-test -c 2
2, make sound and recorded, replay the file:
$ arecord -f cd test.wav
$ aplay test.wav
3, press speaker-mute and mic-mute key, the OSD are shown,
and the LED is on when it's muted.
4, plugin headset and restest the steps above for sound input and output.
sound ctl led is not controlled by headset, it's by design:
please refer to:

[Where problems could occur]
It may break cirrus audio support.

The patches are in v6.16-rc6, Questing already got them.
SRU for OEM-6.14/Plucky those support new these platform.
