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.

+KS7010 Linux driver
+===================
+
+This driver is based on source code from the Ben Nanonote extra repository [1]
+which is based on the original v007 release from Renesas [2]. Some more
+background info about the chipset can be found here [3] and here [4]. Thank
+you to all which already participated in cleaning up the driver so far!

+TODO
+----
+
+First a few words what not to do (at least not blindly):
+
+- don't be overly strict with the 80 char limit. Only if it REALLY makes the
+  code more readable
+- No '#if 0/1' removal unless the surrounding code is understood and removal is
+  really OK. There might be some hints hidden there.
+
+Now the TODOs:
+
+- fix codechecker warnings (checkpatch, sparse, smatch). But PLEASE make sure
+  that you are not only silencing the warning but really fixing code. You
+  should understand the change you submit.
+- drop using a config file and use an upstream technique for configuration
+- fix the 'card removal' event when card is inserted when booting
+- driver crashes when removing the card
+- check what other upstream wireless mechanisms can be used instead of the
+  custom ones here
+
+Please send any patches to:
+Greg Kroah-Hartman <gregkh@linuxfoundation.org>
