880f5b3882 remoteproc: Pass type of shutdown to subdev remove
remoteproc instances can be stopped either by invoking shutdown or by an
attempt to recover from a crash. For some subdev types it's expected to
clean up gracefully during a shutdown, but are unable to do so during a
crash - so pass this information to the subdev remove functions.

2deb41b245 remoteproc updates for v4.16
This contains a few bug fixes and a cleanup up of the resource-table handling
 in the framework, which removes the need for drivers with no resource table to
 provide a fake one.

4f6fd5a037 remoteproc: Drop dangling find_rsc_table dummies
As the core now deals with the lack of a resource table, remove the
dangling custom dummy implementations of find_rsc_table from drivers.

7151202b64 rpmsg updates for v4.14
This extends the Qualcomm GLINK implementation to support the additional
 features used for communicating with modem and DSP coprocessors in modern
 Qualcomm platforms.
 
 In addition to this there's support for placing virtio RPMSG buffers in
 non-System RAM.

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).
