ath9k_hw: split the generic hardware code by hardware family
Browse files Browse the repository at this point in the history 
Move out the generic hardware family code out into their own
files, we have one for AR5008, AR9001, and AR9002 family (ar9002_hw.c)
and another file for the new AR9003 hardware family (ar9003_hw.c).
