Subject: [PATCH] arm64: dts: qcom: msm8916-acer-a1-724: Add sound and modem

Enable sound and modem for Acer Iconia Talk S A1-724.
The setup is similar to most MSM8916 devices, i.e.:

- QDSP6 audio
- Earpiece/headphones/microphones via digital/analog codec in
  MSM8916/PM8916
- WWAN Internet via BAM-DMUX
