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.
