Subject: [PATCH 3/3] arm64: dts: qcom: acer-aspire1: Add sound

This laptop has two i2s speakers; an i2s audio codec for the headset
jack; two DMIC microphones in the lid and the displayport audio channel.

This commit adds the audio node that describes all of the above with the
exception of the DMICs that require in-SoC digital codec to be brought
up, which will be done later.

Note that the displayport channel is connected here for completeness,
but the displayport can't be used yet since the HPD signal is created by
the embedded controller, which will be added later.
