The transmission power is invalid with RFM95 module

[disk91]

The radio.c configPower function does not configure the RFM95 sx1276 module correctly. The power consumption show the PA is activated at +20dB during transmission even if the function parameter is requesting +14dB configuration.

For 14dB configuration a different setting make sense based on RFO instead of PA_Boost.

Actually I've not been able, yet, to find a working configuration for 10dB - 14dB with RFO use on RFM95 module. Any help welcome. Sound like this reported in May 2017 has not been taken into account: RegPaDac register number is defined as 0x5A but it should be 0x4D

Note => +20dB in Europe is not regulation compliant
