ath9k: add power per-rate tables for AR9002 chips
Add TX power per-rate tables for MIMO/legacy modes for AR9002 based chips
in order to cap the maximum TX power value per-rate in the TX descriptor path.
Add TX power adjustments for HT40 mode, open loop CCK rates and eeprom power
bias for AR9280 and later chips
