arm64: dts: qcom: msm8916-samsung-serranove: Add sound and modem

Enable sound and modem for the Samsung S4 Mini Value Edition. The setup
is similar to most MSM8916 devices, i.e.:

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

except:

 - Samsung-specific audio jack detection (not supported yet)
