Current implementation of RT6352 support provides too high tx power at least on iPA/eLNA devices. Reduce amplification of variable gain amplifier by 6dB to match board target power of 17dBm. Transmited signal strength with this patch is similar to that of stock firmware or pandorabox firmware. Throughput measured with iperf improves. Device tested: Xiaomi Miwifi Mini.
