NOTE: This patch series depends on "pinctrl: exynos: Prepare for other
SoCs support" series [1]. It should be applied first.

Add Exynos850 SoC and WinLink's E850-96 board support. A short overview
of series additions and modifications:
  * USI driver: configures UART block
  * PMU driver: connects AP UART lines to uart1 pins)
  * Exynos850 clock driver: generates UART clocks
  * Exynos850 pinctrl driver: mux UART pins
  * serial_s5p: UART driver
  * Exynos850 SoC: dtsi files and MMU maps
  * E850-96 board: dts files, defconfig, board file and doc

Most of the code was borrowed from mainline Linux kernel (where this
board is already enabled) and adapted for U-Boot. Preliminary
preparation for this series includes next patches / series (already
merged):

  * commit 585a2aaac2ac ("arm: exynos: Include missing CPU header in
                          soc.c")
  * commit c9ab9f30c8e4 ("arm: exynos: Include missing CPU header in
                          gpio.h")
  * commit 11bd2787deff ("watchdog: s5p_wdt: Include missing CPU
                          header")
  * commit 08cfa971a717 ("exynos: Avoid duplicate reset_cpu with
                          SYSRESET enabled")
  * commit f655090901dc ("clk: exynos: Add header guard for clk-pll.h")
  * commit 2227f4c0afed ("serial: s5p: Fix clk_get_by_index() error code
                          check")
  * commit a0615ffc99a5 ("serial: s5p: Remove common.h inclusion")
  * commit 5ad21de6bae0 ("serial: s5p: Use livetree API to get "id"
                          property")
  * commit e79f630dbf67 ("serial: s5p: Use named constants for register
                          values")
  * commit a627f2802a71 ("serial: s5p: Improve coding style")
  * commit 33e7ca5a9b6a ("serial: s5p: Use dev_read_addr_ptr() to get
                          base address")
  * commit 6219b47c4d91 ("board: samsung: Fix SYS_CONFIG_NAME configs in
                          axy17lte Kconfig")
  * commit 470682ace1e0 ("configs: Remove unneeded SYS_CONFIG_NAME from
                          a*y17lte defconfigs")

and series [1] (dependency) is still pending.

For more detailed description please see the board documentation (added
in PATCH #12) and corresponding commit messages.
