arm64: dts: qcom: x1e80100-crd: add sound card
Commit Message
Add sound card to X1E80100-CRD board and update DMIC supply.
Full schematics are not available and the limited available parts
suggest that DMIC0-1 use BIAS3 and DMIC2-3 use BIAS1. The DMIC supply
is unknown except one remark for VREG_L1B that it is "used for DMIC if
no WCD".

says it looks sane..

I managed to get DMICs working (to my surprise!), so I will send v2 with
Rb tag and updates.
Best regards,
