[v4,0/7] arm64: dts: exynos: Add E850-96 board support

Message

WinLink's E850-96 is a dev board based on Exynos850 SoC [1]. The board's
design follows 96boards specifications, hence it's compatible with
96boards mezzanines [2].

This patch series adds the initial support for E850-96 board and
Exynos850 SoC, along with corresponding bindings. Only basic platform
components are enabled at the moment (like serial, I2C, eMMC, RTC, WDT,
clock driver, etc). Right now with this patch series it's possible to
run the kernel with BusyBox rootfs as a RAM disk. More features are
coming soon.
