ath9k_hw: define antenna diversity group

AR9285 belongs to diversity group 0 and AR9485 belongs to diversity group 2. Based on the diversity group we configure certain antenna diversity paramaters such as lna1_lna2_delta and fast diversity bias values. For AR9485 we have some gain table parameter which selects the gain table 0/1 for main and alternate antenna Cc: Gabriel Tseng <[email protected]> Cc: Senthilkumar Balasubramanian <[email protected]> Signed-off-by: Mohammed Shafi Shajakhan <[email protected]> Signed-off-by: John W.
