Subject: [PATCH v2 3/4] arm64: dts: qcom: msm8916-samsung-j5: Use common device tree

The smartphones below are using the MSM8916 SoC,
which are released in 2015-2016:

Samsung Galaxy J5 2015 (SM-J500*)
Samsung Galaxy J5 2016 (SM-J510*)
Samsung Galaxy J3 2016
- SM-J3109/SM-J320Y/SM-J320YZ
- SM-J320N0/SM-J320ZN
- SM-J320P/SM-J320R4/SM-J320V/SM-S320VL

The three devices (some varints of J3, all other variants of J5 released
in 2015 and J5X released in 2016) are very similar, with some differences
in display and GPIO pins. The common parts are shared in
msm8916-samsung-j5-common.dtsi to reduce duplication.
