Subject: [PATCH] dt-bindings: iio: samsung,exynos-adc: add common clock properties

Add common properties appearing in DTSes (assigned-clocks and similar)
to fix dtbs_check warnings like:

  arch/arm/boot/dts/exynos3250-artik5-eval.dt.yaml:
    adc@...c0000: assigned-clock-rates: [[6000000]] is not of type 'object'
  arch/arm/boot/dts/exynos3250-artik5-eval.dt.yaml:
    adc@...c0000: assigned-clocks: [[7, 238]] is not of type 'object'

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