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.

spilib is used by multiple users currently (spi.c and fw-core.c) but
commit aa52b62a0556 broke that hierarchy and introduced gbphy dependent
code in spilib.
This may have unreliable consequences as we are doing following
operation unconditionally now:
gbphy_dev = to_gbphy_dev(spi->parent);
gbphy_runtime_get_sync(gbphy_dev);
which may not go well when the parent is of type &bundle->dev
(fw-core.c).
This patch introduces spilib_ops and lets the users of the core register
them. This shall have no functional change for the spi.c usecase and
shall fix the unreliable results for the fw-core.c usecase.
Tested by writing to mtd0 dev and verifying (with print messages) that
the below routines are getting called for a gpbridge-test module.
Fixes: aa52b62a0556 ("spi: Add runtime_pm support")

This patch restructures spi.c as spilib core, so that the same logic can
be reused for SPI connections implemented as part of different bundle
types. This is required for Firmware Management Bundle.
Note that the 'struct gb_protocol' and its callback aren't moved to
a separate file in this commit to make its reviews easier. That will be
done by a following patch.
