arm64: dts: qcom: msm8916-samsung-j3ltetw: Add initial device tree

Browse Source 
The dts and dtsi add support for msm8916 variant of Samsung Galaxy J3
SM-J320YZ smartphone released in 2016.

Add a device tree for SM-J320YZ with initial support for:

- GPIO keys
- SDHCI (internal and external storage)
- USB Device Mode
- UART (on USB connector via the SM5703 MUIC)
- WCNSS (WiFi/BT)
- Regulators
- QDSP6 audio
- Speaker/earpiece/headphones/microphones via digital/analog codec in
  MSM8916/PM8916
- WWAN Internet via BAM-DMUX
- Touchscreen
- Accelerometer

There are different variants of J3, with some differences in MUIC, sensor,
NFC and touch key I2C buses.

The common parts are shared in msm8916-samsung-j3-common.dtsi to reduce
duplication.
