[ath9k-devel] [PATCH] ath9k: Update AR9340 initvals for txgain table mode 4

Changing the table for 5Ghz HT20/HT40 to fix a 10dbm signal difference
on the client side when running LEDE on the AP (TpLink CPE510) instead
of the vendor driver. These values are taken from a TpLink CPE510 running
the vendor firmware using a small script that retrieved the same registers
as already defined in the tx gain table.

Because I don't have any datasheets about this wireless chip I can not
really say, what I'm changing.
