alsa/sdw: add support for tgl_3_in_1_sdca soundwire machine

[Hui Wang]

[Impact]
We need to enable a Dell soundwire machine in the OEM project, but
the soundwire design is different from previous generation, it follows
soundwire sdca spec. both ubuntu kernel and upstream kernel don't have
driver for soundwire sdca yet, so the audio device on this machine
can't be detected.

[Fix]
backport 20 patches from the kernel git tree of intel sof/project

[Test]
After booting up, we could see the sound card by running
pacmd list-cards, and there is speaker, headphone, dmic and headset-mic
on this sound card, test playback and record, all worked well.

[Where problems could occur]
The patches change some soundwire bus driver and alsa intel asoc
machine driver, it could make the sound stop working on old
soundwire machines. But this possibility is very low since we
tested these patches on Dell soundwire machines.

Is this bug relevant to Dell Latitude 9510? It appears that the sound card is not detected using 5.10.0-1009.10 kernel. I attached my alsa-info just in case.

The bug is not for Dell Latitude 9510, please open a public Launchpad bug for Dell Latitude 9510.
I saw your alsa-info, the driver is not correct, maybe you can try module parameter 'snd_intel_dspcfg: dsp_driver=3' first.

Thanks,
