Now that the SPDX tag is in all fbtft 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.
Fix up the all of the staging fbtft drivers 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.

Having a local variable of 1024 bytes on 64-bit architectures is a bit
too much, and I ran into this warning while trying to see what functions
use the largest stack:
drivers/staging/fbtft/fbtft-sysfs.c: In function 'store_gamma_curve':
drivers/staging/fbtft/fbtft-sysfs.c:132:1: warning: the frame size of 1032 bytes is larger than 1024 bytes [-Wframe-larger-than=]
As there is no need for 64-bit gamma values (on 32-bit architectures,
we don't use those either), I'm changing the type from 'unsigned long'
to 'u32' here, which cuts the required space in half everywhere.
