[PATCH 2/2] arm64: dts: qcom: msm8939-huawei-kiwi: Add initial device tree

[Lukas Walter <lukas.walter@aceart.de>]

This dts adds support for Huawei Honor 5X / GR5 (2016) smartphone
released in 2015.

Add device tree with initial support for:

- GPIO keys
- Hall sensor
- SDHCI (internal and external storage)
- WCNSS (BT/WIFI)
- Sensors (accelerometer and proximity)
- Vibrator
- Touchscreen
