ath79: enable LNA for all ar9344 TPLink CPE devices
The TPLink CPE devices CPE210/CPE510 based on ar9344 have a build-in
Low Noise Amplifier on both of the 2x2 mimo rx chains.
This patch activates those two LNAs in the respective receiving chains
and hence improves the RX sensitivity by about 20dB.
Tested on CPE510 v2 & v3.
