Subject: [PATCH 4/4] ath: Fix ath_dbg access beyond array bound

ar9300RateSize is not necessarily a power of 4.

Change ar9003_hw_set_target_power_eeprom
to print the targetPowerValT2 array one per line.

ath9k_hw_ar9300_set_txpower repeated the output 4 times per line,
change it to print the targetPowerValT2 value one per line.
