The ssr_notifiers variable should be local, so add the missing static
storage classifier.

1e140df049 remoteproc: qcom: Add support for SSR notifications
This adds the remoteproc part of subsystem restart, which is responsible
for emitting notifications to other processors in the system about a
dying remoteproc instance.

These notifications are propagated to the various communication systems
in the various remote processors to shut down communication links that
was left in a dangling state as the remoteproc was stopped (or crashed).

In preparation for moving the mdt loader out of remoteproc let's move
the somewhat unrelated resource table dummy helper to a Qualcomm
"common" file.
