Convert the rtc-cmos devicetree bindings to dt schema. The original text binding documents only the motorola,mc146818 compatible. Existing in-tree Devicetree sources also use the intel,ce4100-rtc compatible together with the motorola,mc146818 fallback, but this was not documented. Document the Intel variant in the schema so that these existing configurations are accepted during schema validation.
