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.

The firmware file name's maximum length is set to 56 right now, but it
isn't very much readable how we got to that value (unless someone reads
that line).
Update the comment to show calculations.

Alex Elder pointed out that the macros also count the trailing NULL
('\0') character and so it should be using SIZE instead of LEN.
This patch makes that change.

Replace prefix "ara_" with prefix "gmp_" for TFTF firmware filenames.
Testing Done: compiled and flashed EVT2 (bootimage) and tested that
"gmp_" prefixed tftf files are expected. Pushed one from
FDK and checked that it's properly loaded.

The firmware prefix is hard-coded in a few different places. Put it all
in one handy #define, for when/if we ever decide to change it in the
future...
Testing: 'strings gb-firmware.ko gb-bootrom.ko | grep ara_' produced the
same output before and after this patch.

This patch adds Component Authentication Protocol support in greybus.
The purpose of the CAP protocol is to authenticate the Module hardware,
and it can only be used when it is present as part of the
firmware-management bundle, on a separate CPort.
Compile tested only.

Convert the legacy firmware protocol driver to a bundle driver.
This also fixes a potential crash should a (malicious) module have sent
an early request before the private data had been initialised.
Note that the firmware protocol needs to support the version request
indefinitely since it has been burnt into ROM.
In order to avoid having to update current module-loading scripts, keep
this driver internal to greybus core at least until modalias support is
added.
Note that there is no MODULE_DEVICE_TABLE defined for firmware as we
cannot have two greybus tables in one module on ancient 3.10 kernels and
that the legacy driver is currently also internal to core. This needs be
added once the driver can be built as a module.
Testing Done: Tested on DB3.

This adds firmware protocol driver based on the latest specs available
on mailing lists. This uses the firmware framework present in kernel.
Refer Documentation/firmware_class/README on how it works.
