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.
