soc: qcom: glink_ssr: Add support for ss_info without notify edges 



In probe function ss_info requires atleast one notify edge in order
to register for subsystem restart notification callback.

Add support for ss_info to register for subsystem restart notification
callback even if there is no edge to notify.
