ath9k: Remove incorrect diversity initialization
Fast antenna diversity is required only for single chain chips and the diversity initialization is done in the per-family board setup routines. Enabling of diversity should be done based on the calibrated EEPROM/OTP data, doing it for all chips is incorrect. Remove the code that sets the fast_div bit for all cards, since the documentation for the AR_PHY_CCK_DETECT register says: reg 642: sig_detect_cck enable_ant_fast_div : Only used for single chain chips.
