arm64: dts: qcom: x1e78100-t14s: add sound support

Add support for audio on Lenovo T14s laptop, coming with two speakers,
audio jack and two digital microphones.

This is very early work, not yet complete:
1. 2x speakers: work OK.
2. 2x digital microphones: work OK.
3. Headset (audio jack) recording: does not work.
4. Headphones playback (audio jack): channels are intermixed.

[krzysztof: correct DMIC routing and vamacro pinctrl, re-order nodes,
 add commit msg]
