We need to ensure that all consumers of the GPIO/I2C controllers remain in the deferred state until the remote processor is fully online. For instance, consider a regulator node that references a GPIO line from the RPMSG GPIO controller. The regulator will stay in the deferred state until the remote processor comes online and its services are announced and received.

Until then, the GPIO driver will remain in a deferred state, ensuring that all consumers of the associated GPIOs are also deferred. The implementation you provided below does not guarantee that the related consumers will be properly deferred. This is the most important behavior for a GPIO/I2C controllers.
