arm64: dts: qcom: msm8916-samsung-j3ltetw: Add initial device tree v2 PROPOSED

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.

Please do not work on old kernels... You *must* base on something recent.

<form letter>
Please use scripts/get_maintainers.pl to get a list of necessary people
and lists to CC (and consider --no-git-fallback argument). It might
happen, that command when run on an older kernel, gives you outdated
entries. Therefore please be sure you base your patches on recent Linux
kernel.

Tools like b4 or scripts/get_maintainer.pl provide you proper list of
people, so fix your workflow. Tools might also fail if you work on some
ancient tree (don't, instead use mainline) or work on fork of kernel
(don't, instead use mainline). Just use b4 and everything should be
fine, although remember about `b4 prep --auto-to-cc` if you added new
patches to the patchset.
</form letter>
