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
