Commit Message

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@linaro.org>

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