[PATCH] dt-bindings: arm: samsung: Do not require clkout on Exynos5260 and Exynos7

The PMU (Power Management Unit) driver is a clkout clock provider (for
clock signal monitoring) only for certain Exynos SoCs. It was never
implemented for Exynos5260 and Exynos7. This fixes dtschema validator
warnings like:

system-controller@105c0000: '#clock-cells' is a required property
