staging: ks7010: add SPDX identifiers to all files

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 ks7010 files 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.

Extra GPL text wording can be removed as it is no longer needed at all.

staging: ks7010: remove WPS definition conditional code

WPS definition was defined by default in ks_wlan.h header
file. So it makes no sense to have conditional preprocessor
stuff along the code about this.

staging: ks7010: add parentheses to complex macro

Checkpatch emits ERROR: Macros with complex values should be enclosed
in parentheses. Error may be fixed by adding parentheses around macro
definition, macros are simple arithmetic statement.

Add parentheses around macro definitions. Fix 24 cases of identical
error. Do commented out macros also to save the next developer from
having to add them.

Staging: ks7010: Remove extern keyword from function declaration

Remove extern specifier from function declaration as they have
it by default. Also move extern declaration from .c files to
their respective header file 'ks_hostif.h'. Coccinelle was used
to remove extern and other changes were done by hand.

staging: ks7010: add driver from Nanonote extra-repository

See the TODO for details where this driver came from. Only a few minor
changes were made to make the driver suitable for staging:

* updated Kconfig help text and dependencies
* added TODO
* removed two __DATE__ and __TIME__ printouts to allow reproducible builds
* added to staging main Kconfig + Makefile

Tested on a Renesas Salvator-X board with a Spectec SDW-823 card. I
could connect to a WPA-protected network.
