Revert "ath9k_hw: Update AR9003 high_power tx gain table"

commit 9c170e068636deb3e3f96114034bb711675f0faa upstream.

This reverts commit f74b9d365ddd33a375802b064f96a5d0e99af7c0.

Turns out reverting commit a240dc7b3c7463bd60cf0a9b2a90f52f78aae0fd
"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

ath9k: ar9003: fix OTP register offsets for AR9340

commit b3cd8021379306c0be6932e4d3b4b01efc681769 upstream.

Trying to access the OTP memory on the AR9340
causes a data bus error like this:

  Data bus error, epc == 86e84164, ra == 86e84164

The cause of the error is that the OTP register
offsets are different on the AR9340 than the
actually used values.
