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.
