arm64: dts: qcom: msm8916-alcatel-idol347: Add sound and modem

Enable sound and modem for the Alcatel Idol 3 (4.7"). The setup is
similar to most MSM8916 devices, i.e.:

 - QDSP6 audio
 - Microphones via digital/analog codec in MSM8916/PM8916
 - WWAN Internet via BAM-DMUX

except:

 - Stereo NXP TFA9890 codecs for speakers on Quaternary MI2S
   - These are also used as earpieces at the top/bottom.
 - Asahi Kasei AK4375 headphone codec on Secondary MI2S
 -> Primary MI2S is not used for playback
