remoteproc: qcom: pas: Fix subdevice add order
Currently, the notification like QCOM_SSR_BEFORE_SHUTDOWN is not exactly sent before starting shutdown activity on remote subsystem but it is getting sent after sysmon shutdown request to remote. On getting QCOM_SSR_BEFORE_SHUTDOWN, some client want remote subsystem to be alive to communicate but as sysmon shutdown request is getting sent to remote before QCOM_SSR_BEFORE_SHUTDOWN notification sent to kernel client due to which remote is not in a condition to communicate with kernel clients. Fixing the subdevice ordering will fix this as ssr subdevice will be first one to get triggered in shutdown/stop path.
