[PATCH 12/12] arm64: dts: exynos: Add initial support for Samsung Galaxy S9 (SM-G960F)

[Markuss Broks <markuss.broks@xxxxxxxxx>]

Samsung Galaxy S9 (SM-G960F), codenamed starlte, is a mobile phone
released in 2017. It has 4GB of RAM, 64GB of UFS storage, Exynos9810
SoC and 1440x2960 Super AMOLED display.

This initial device tree enables the framebuffer pre-initialised
by bootloader and physical buttons of the device, with more support
to come in the future.
