09956d59ba staging: clocking-wizard: remove redundant license text
Now that the SPDX tag is in the clocking-wizard driver 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.

1dbb3344d9 staging: clocking-wizard: add SPDX identifier.
It's good to have SPDX identifiers in all files to make it easier to
audit the kernel tree for correct licenses.

Fix up the staging clocking-wizard driver to have a proper SPDX
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 clk_name gets the return value from kasprintf (part of which does the
allocation of the returned buffer). So check the return pointer
before using it for clk_register_fixed_factor.
