[PATCH v2 4/4] dt-bindings: soc: samsung: exynos-sysreg: add clocks for Exynos850

[Krzysztof Kozlowski]

Exynos850 has dedicated clock for accessing SYSREGs.  Allow it, even
though Linux currently does not enable them and relies on bootloader.

Signed-off-by: Krzysztof Kozlowski <krzysztof.kozlowski at linaro.org>

Changes since v1:
1. Make clocks required on Exynos850.
2. Due to above change, do not add Rb tags.
