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.
