Subject: [PATCH v6 2/5] arm64: dts: qcom: msm8916-samsung-j5-common: Add initial 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*)

Move msm8916-samsung-j5.dts to msm8916-samsung-j5-common.dtsi, and add
a common device tree for 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

The two devices (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.

This patch rewrites J5 2015 devices, later patches will add support for
other models.
