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.

On ChromeOS systems with USB Type C ports, the ChromeOS Embedded Controller is
|
|
able to detect the state of external accessories such as display adapters
|
|
or USB devices when said accessories are attached or detached.
|
|
The node for this device must be under a cros-ec node like google,cros-ec-spi
|
|
or google,cros-ec-i2c.
