Revert "ath9k_hw: Update AR9003 high_power tx gain table"

This reverts commit 4de2b3ddf39a67451bcde739e340671f58561723.

Turns out reverting commit 85cb659518c72e4f786442077c60ed299a0219f1
"ath9k_hw: Updated AR9003 tx gain table for 5GHz" was not enough to
bring the tx power back to normal levels on devices like the
Buffalo WZR-HP-G450H, this one needs to be reverted as well.

This revert improves tx power by ~10 db on that device
