arm: exynos: Add Exynos850 SoC support
Samsung Exynos850 is ARMv8-based mobile-oriented SoC. It features
Cortex-A55 CPU (8 cores) and it's built using 8nm process.
Add Exynos850 support by enabling next features:
* Import Exynos850 SoC dtsi files from Linux kernel
* Add Exynos850 MMU memory map
* Introduce ARCH_EXYNOS9 platform config option
