[PATCH 5/7] arm64: dts: qcom: add device tree for Xiaomi Redmi Note 5 Pro (whyred)

[Gianluca Boiano <morf3089@gmail.com>]

Add initial device tree support for the Xiaomi Redmi Note 5 Pro
(codename: whyred), a smartphone based on Qualcomm SDM636 SoC with
4/6GB RAM and a 5.99" 1080x2160 display.

This enables:
- Booting to a framebuffer console
- USB support
- Hall effect sensor
- Touchscreen (Synaptics RMI4)
- Battery monitoring
- Charging (pm660_charger)
- Status LED (pm660l_lpg)
