Some Chromebooks use a separate wake pin, while others overload the interrupt for wake and IO. With the current assumption, spurious wakes can occur on systems that use a separate wake pin. It is planned to update the driver to no longer assume that the EC interrupt pin should be enabled for wake. Add the wakeup-source property to all cros-ec-spi compatible device nodes to signify to the driver that they should still be a valid wakeup source.
