Many source files in the tree are missing licensing information, which
makes it harder for compliance tools to determine the correct license.

By default all files without license information are under the default
license of the kernel, which is GPL version 2.

Update the files which contain no license information with the 'GPL-2.0'
SPDX license identifier.  The SPDX identifier is a legally binding
shorthand, which can be used instead of the full boiler plate text.

This patch is based on work done by Thomas Gleixner and Kate Stewart and
Philippe Ombredanne.

How this work was done:

Patches were generated and checked against linux-4.14-rc6 for a subset of
the use cases:
 - file had no licensing information it it.
 - file was a */uapi/* one with no licensing information in it,
 - file was a */uapi/* one with existing licensing information,

Further patches will be generated in subsequent months to fix up cases
where non-standard...

Introduce the GLINK subdev, which allows the definition of a GLINK edge
as child of a remoteproc.

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).

Move the SMD edge handling to the Qualcomm common file to make it
reusable for other Qualcomm remoteproc drivers.

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.
