dt-bindings: memory-controllers: samsung,exynos4210-srom: Enforce child props

Samsung Exynos SROM peripheral properties were moved from the device
schema to separate "peripheral-props" schema for child node, but the
device schema does not reference the new one.

Reference the peripheral-props schema so the child nodes will be
properly validated from the device schema.
