staging: ks7010: Remove unused driver

Wolfram contributed this driver in 2016. He is not using it anymore and
confirmed it to be removed.

It is hard to find hardware around the globe. When it is offered it is
expensive and performance is low.

Remove unused driver.

-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
-
-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.
-- fix the 'card removal' event when card is inserted when booting
-- check what other upstream wireless mechanisms can be used instead of the
-  custom ones here
-- Switch to use LIB80211.
-- Switch to use MAC80211.
-- Switch to use CFG80211.
