dt-bindings: cros-ec: Reorganize and enforce property availability
Various properties in the cros-ec binding only apply to different compatible strings. For example, the interrupts and reg property are required for all cros-ec devices except for the rpmsg version. Add some conditions to update the availability of properties so that they can't be used with compatibles that don't support them. This reveals that many of the examples in bindings that use cros-ec were missing the interrupts property. Add the property to make those bindings whole again.
