ath: Add config option for DFS support

Browse Source 
This patch adds a config option to enable DFS in ath9k and ath10k
drivers (with ath10k you need the AP-branch firmware). I'm not entirely
sure about the regulatory compliance issues, though. As far as I
understand, enabling the DFS_CERTIFIED config options implies that the
device is certified for DFS. No doubt the original firmware has obtained
such a certification, but not with the open source drivers. I suppose
that as long as this is disabled in default builds (like ATH_USER_REGD)
everything should be fine, but it would be nice to have out-of-the-box
OpenWrt support for DFS. I'm also not sure whether the description of
the configuration option should say something about regulatory compliance.

Say Y, if you want to debug atheros wireless drivers.
Right now only ath9k makes use of this.

help
Dynamic frequency selection (DFS) is required for most of the 5 GHz band
channels in Europe, US, and Japan.
Select this option if you want to use such channels. Only EU (ETSI) DFS
is supported at the moment.
