Now that the SPDX tag is in all greybus files, that identifies the
license in a specific and legally-defined manner. So the extra GPL text
wording can be removed as it is no longer needed at all.
This is done on a quest to remove the 700+ different ways that files in
the kernel describe the GPL license text. And there's unneeded stuff
like the address (sometimes incorrect) for the FSF which is never
needed.
No copyright headers or other non-license-description text was removed.

It's good to have SPDX identifiers in all files to make it easier to
audit the kernel tree for correct licenses.
Update the drivers/staging/greybus files files with the correct SPDX
license identifier based on the license text in the file itself. The
SPDX identifier is a legally binding shorthand, which can be used
instead of the full boiler plate text.
This work is based on a script and data from Thomas Gleixner, Philippe
Ombredanne, and Kate Stewart.

No need to support older kernel versions in the Greybus Vibrator driver,
so remove the checks as needed, we can now rely on all of the correct
driver core apis being present.

In the beginning, module side can control the vibrator timeout value,
it can disable vibrator until timeout. But after Runtime PM control added
in, AP side didn't know when module can be suspended, the vibrator
task will be interrupted by suspending event.
Because of this problem, the module can not be in charge of counting down
the timeout value, it is now up to the AP to manage this. So add workqueue
to handle the vibrator timeout.

We don't use these anymore. Drop them.
Note that some macro's specific to bridged PHY devices aren't removed in

separately.

We are removing struct device from the gb_connection structure in the
near future. The gb_bundle structure's struct device should be used as
a replacement.
This patch moves the vibrator driver to use the bundle pointer instead
of the connection pointer.

idr and ida structures have internal memory allocated that needs to be
freed when modules are removed. So call the proper idr_destroy() or
ida_destroy() functions on the module exit path to free the memory.

All we need is a simple ida, so use that interface instead of the more
"complex" idr one. Bonus is we don't need to fix the locking issue I
forgot about when using an idr, as ida has one built-in.

All protocols use the same value to distinguish between request and
response message types. This is a requirement.
Use GB_MESSAGE_TYPE_RESPONSE rather than GB_OPERATION_TYPE_RESPONSE
for the name of the flag used to distiguish between request and
response messages.
Get rid of the redundant response flag definitions that are
associated with specific protocols.
Describe the symbolic values as "operation types" rather than
"message types" where they are defined. The message type for a
request is the same as the operation type; the message type for a
response is the operation type OR'd with GB_MESSAGE_TYPE_RESPONSE.

Some files are still prefixed with "gb-" with the reasoning that the modules
would be named so, i.e. gb-*.ko. But this can be done by playing a bit in
Makefile instead and keep uniform naming of .c files.
Lets try it.
