ath9k: change DFS logging to use ath_dbg()
The DFS pattern detector was initially planned to reside on
a higher layer and used generic pr_*() logging functions.
Being part of ath9k, use ath_dbg() instead and make DFS log
ouput selectable via ATH_DBG_DFS (0x20000) at runtime.
This patch does not contain functional modifications.
