Convert Samsung Exynos System Registers (SYSREG) bindings to DT schema
format using json-schema.
Signed-off-by: Krzysztof Kozlowski <krzk@xxxxxxxxxx>

Changes since v2:
1. Use select to skip other syscon nodes,
2. Indent example with four spaces (more readable),

-SAMSUNG S5P/Exynos SoC series System Registers (SYSREG)
-
-Properties:
- - compatible : should contain two values. First value must be one from following list:
- - "samsung,exynos4-sysreg" - for Exynos4 based SoCs,
- - "samsung,exynos5-sysreg" - for Exynos5 based SoCs.
- second value must be always "syscon".
- - reg : offset and length of the register set.
-
-Example:
- syscon@10010000 {
- compatible = "samsung,exynos4-sysreg", "syscon";
- reg = <0x10010000 0x400>;
- };
-
- syscon@10050000 {
- compatible = "samsung,exynos5-sysreg", "syscon";
- reg = <0x10050000 0x5000>;
- };
