Sending state of remoteprocs booting up in parallel can cause a race between SSR clients of the remoteproc that is booting up and the sysmon notification for the same remoteproc, resulting in an inconsistency between which state the remoteproc that is booting up in parallel. For example - if remoteproc A and B crash one after the other, after remoteproc A boots up, if the remoteproc A tries to get the state of remoteproc B before the sysmon subdevice for B is invoked but after the ssr subdevice of B has been invoked, clients on remoteproc A might get confused when the sysmon notification indicates a different state.
