staging: remove the Atheros otus vendor driver

Atheros originally had posted a vendor driver to support
the Atheros AR9170 devices, the driver was called otus [1].
The otus driver was staging quality but it, along with
other chipset documentation helped the community do a rewrite
for a proper driver. Johannes Berg did the ar9170 [2] work and
Christian Lamparter then followed up with some final touches
for inclusion upstream.

The original goal behind ar9170 was to match all functionality,
performance, stability and quality against Otus. In the end this
proved quite challenging even with GPLv2 firmware.

Christian then decided to work on a replacement driver with
new enhancements to the GPLv2 firmware. It took 1 year, 5 months,
9 days since this merge of ar9170usb upstream to release carl9170
with upstream inclusion intentions but its now there.

We remove the Otus driver now as the carl9170 driver actually
ends up not only replacing but superseding the staging Otus driver!

-	depends on USB && WLAN && MAC80211
-	select WIRELESS_EXT
-	select WEXT_PRIV
-	default N
-	---help---
-	  Enable support for Atheros 802.11n USB hardware:
-	    * UB81 - 2x2 2.4 GHz
-	    * UB82 - 2x2 2.4 GHz and 5 GHz
-	    * UB83 - 1x2 2.4 GHz
-
-	  This includes the following devices currently on the market:
-	  Dlink DWA-160A1, Netgear WNDA3100 and WN111v2, TP-Link
-	  TL-WN821N, and AVM FRITZ!WLAN N USB Stick.
-
-	  This driver requires its own supplicant driver for
-	  wpa_supplicant 0.4.8. For your convenience you can find the
-	  tarball here:
-
-	  http://www.kernel.org/pub/linux/kernel/people/mcgrof/otus/wpa_supplicant-0.4.8_otus.tar.bz2
-
-	  Before compiling wpa_supplicant, ensure your .config has at
-	  least the following:
-		CONFIG_WIRELESS_EXTENSION=y
-		CONFIG_EAP_WSC=y
-		CONFIG_WSC_IE=y
-		CONFIG_DRIVER_WEXT=y
-		CONFIG_DRIVER_OTUS=y
-
-	  After a successful compile, you can use the Atheros device as
-	  shown in the example:
-	  $ wpa_supplicant -Dotus -i <atheros device from ifconfig> -c /path/to/wpa_supplicant.conf -d
-
