ath9k_hw: allow for spliting up ANI operations by family

The AR9003 hardware family will use a slightly modified ANI
implementation which has not yet been tested on the other hardware
families. To allow for this new ANI implementation a few ANI
calls need to be abstracted away. This patch just allows for
each hardware family to declare their own ANI ops and annotates
the current ANI implementation as old.
