Subject: [PATCH v5 10/10] arm64: dts: exynos: Add initial support for Samsung Galaxy S8

Samsung Galaxy S8 (SM-G950F), codenamed dreamlte, is a mobile phone
from 2017. It features 4GB RAM, 64GB UFS 2.1, Exynos 8895 SoC and a
1440x2960 Super AMOLED display.

This initial device tree enables SimpleFB, PSTORE and GPIO keys.
