Convert Samsung Exynos System Registers (SYSREG) bindings to DT schema
format using json-schema.

Signed-off-by: Krzysztof Kozlowski <krzk@kernel.org>

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>;
-	};
