ath9k_hw: add DFS testing check

Browse Source 
In order to enable DFS upstream we want to be sure
DFS has been tested for each chipset. Push for public
documentation of the requirements we want in place and
allow for enabling each chipset through a single upstream
commit.

* Once a new chipset gets properly tested an individual commit can be used
* to document the testing for DFS for that chipset.
